Make sure that this instruction manual is delivered to the end user of the inverter unit. 2. Read this manual before installing or operating the inverter unit, and store it in a safe place for reference. Inspection and maintenance Warranty Disposal of the inverter 2004 Ver. 108/109 E6581158 I. Safety precautions The items described in these instructions and on the inverter itself are very important so that you can use the inverter safely, prevent injury to yourself and other people around you as well as to prevent damage to property in the area. Thoroughly familiarize yourself with the symbols and indications shown below and then continue to read the manual. [. . . ] In this case, use the auto-restart function along with this parameter function. F-36 E6581158 [When power is interrupted] Input voltage Output frequency * The time for which the operation of the motor can be continued depends on the machine inertia and load conditions. Before using this function, therefore, perform verification tests. About 100ms [If momentary power failure occurs] Input voltage Output frequency 6. 13. 3 Retry function : Retry selection (Selecting the number of times) Caution · Do not go near the motor in alarm-stop status when the retry function is selected. The motor may suddenly restart, which could result in injury. attach a cover to the motor, to prevent accidents if the motor suddenly restarts. · Function This parameter resets the inverter automatically when the inverter gives an alarm. During the retry mode, the motor speed search function operated automatically as required and thus allows smooth motor restarting. 6 Mandatory [Parameter setting] Title Function Retry selection (number of times) Adjustment range 0: None, 1-10 times Default setting 0 F-37 E6581158 The likely causes of tripping and the corresponding retry processes are listed below. Cause of tripping Retry process Canceling conditions Momentary power Up to 10 times in succession The retry function will be canceled at failure 1st retry: About 1 sec after tripping once if tripping is caused by an unusual Overcurrent 2nd retry: About 2 sec after tripping event other than: momentary power Overvoltage 3rd retry: About 3 sec after tripping failure, overcurrent, overvoltage or Overload overload. Overheating 10th retry: About 10 sec after tripping This function will also be canceled if retrying is not successful within the specified number of times. The retry function is disabled in the following unusual events: · : Arm overcurrent at start-up · : Main unit RAM fault · : Overcurrent on the load side at start-up · : Main unit ROM fault · : Output phase failure · : CPU fault trip · : External thermal trip · : Remote control error · : Overtorque trip · : Current detector fault · : External trip stop · : Control circuit board format error · : Small-current operation trip · : EEPROM fault 1 · : Undervoltage trip (main circuit) · : EEPROM fault 2 · : Ground fault trip · : EEPROM fault 3 · : Input phase failure · : Auto-tuning error · : Inverter type error · : VIA input detection error · : Main unit CPU communication error · : Excessive torque boost · : CPU fault 2 Protective operation detection relay signals (FLA, FLB, FLC terminal signals) are not sent during use of the retry function. (Default setting) To allow a signal to be sent to the protective action detection relay (FLA, B and C terminals) even during the retry process, assign the function 36 or 37 to . A virtual cooling time is provided for overload tripping ( , , ). In this case, the retry function operates after the virtual cooling time and retry time. In the event of tripping caused by an overvoltage ( ), the retry function will not be activated until the voltage in the DC section comes down to a normal level. In the event of tripping caused by overheating ( ), the retry function will not be activated until the temperature in the inverter comes down low enough for it to restart operation. Keep in mind that when is set to (trip retained), the retry function will not be performed, regardless of the setting of . During retrying, the blinking display will alternate between and the monitor display specified by status monitor display mode selection parameter . The number of retries will be cleared if the inverter is not tripped for the specified period of time after a successful retry. "A successful retry" means that the inverter output frequency reaches the command frequency without causing the inverter to re-trip. . . . 6 F-38 E6581158 6. 13. 4 Dynamic (regenerative) braking - For abrupt motor stop : Dynamic braking selection : Dynamic braking resistance : Dynamic braking resistor capacity · Function The VFS11 does not contain a braking resistor. Connect an external braking resistor in the following cases to enable dynamic braking function: 1) when decelerating the motor abruptly or if overvoltage tripping (OP) occurs during deceleration stop 2) when a continuous regenerative status occurs during downward movement of a lift or the winding-out operation of a tension control machine 3) when the load fluctuates and a continuous regenerative status results even during constant speed operation of a machine such as a press [Parameter setting] Title Function Dynamic braking selection Dynamic braking resistance Dynamic braking resistor capacity Adjustment range 0: Disabled 1: Enabled (Resistor overload protection enabled) 1. 0-1000 () 0. 01-30. 00 (kW) Default setting 0 Depending on models (See Section 11, K-15) 6 1) Connecting an external braking resistor (optional) Separate-optional resistor (with thermal fuse) External braking resistor (optional) PBR MCCB R/L1 Three-phase main circuits Power supply S/L2 T/L3 PA PB U/T1 V/T2 W/T3 Inverter Motor IM F-39 E6581158 Connecting thermal relays and an external braking resistor TH-R External braking resistor (optional) PBR MCCB Three-phase main circuits Power supply Step-down transformer 2:1 MC R/L1 R/L2 R/L3 PA PB U/T1 V/T2 W/T3 Motor IM Inverter MC FLB F R Forward Reverse Fuse Power supply TC Surge suppressor FLC FLA CC 6 Note 1: A TC (Trip coil) is connected, as shown in this figure, when an MCCB with a trip coil is used instead of an MC. A step-down transformer is needed for every 400V-class inverter, but not for any 200Vclass inverter. Note 2: As a last resort to prevent fire, be sure to connect a thermal relay (THR).

If defective conditions are encountered, please contact the Toshiba service section in charge via your Toshiba dealer. When making a call for servicing, please inform us of the contents of the rating label on the right panel of the inverter, the presence or absence of optional devices, etc. , in addition to the details of the failure. 14. 4 Keeping the inverter in storage Take the following precautions when keeping the inverter in storage temporarily or for a long period of time. Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder. [. . . ]
