TABLE OF CONTENTS Section i. 2 Relationship of AC Line Input and Motor Voltage with J1, J2 and J3 Positions . [. . . ] To operate in reverse direction, connect to "S0, " "S2, " and "S3. " See fig. Bidirectional operation using reversing contacts ­ Connect to terminals "S0, " "S1, " "S2, " and "S3" as per fig. 9 ­ UNIDIRECTIONAL OPERATION (Reverse) -15V SIG +15V MIN S3 S2 S1 S0 RB1 RB2 FIG. 10 ­ BIDIRECTIONAL OPERATION (Reversing Contact) -15V SIG +15V MIN COM STP FIG. 11 ­ BIDIRECTIONAL OPERATION (Potentiometer) -15V SIG +15V S3 S2 S1 S0 S3 S2 S1 MAIN SPEED POT FWD REV F. Voltage Following ­ An analog voltage can be used in lieu of main speed potentiometer. Connect signal to terminals "S2" and "RB1. " Note: Terminal "RB1" is common. A positive signal with respect to terminal "RB1" will produce a positive output to motor. A negative signal with respect to terminal "RB1" will produce a negative output. A0 to ±10VDC is required to operate control from 0 ± full output. [A bipolar signal isolator, SI-4X (KB P/N 8801), is available as an option from your distributor. ] Note: Jumper J5 must be in the "10V" position. Note: An isolated signal voltage FIG. 12 ­ VOLTAGE FOLLOWING CONNECTION must be used or catastrophic failure can result. Start/Stop Circuits ­ The KBRG-213D contains two 2-wire stop circuits which are used to electronically bring the motor to a "stop. " Both require an isolated single contact closure. If an isolated contact is not available, it may be necessary to use an isolation relay. Do not use Start/Stop or inhibit functions as a safety disconnect. Use only an AC line disconnect for that purpose. 7 i. Regen to stop using terminals RB1 and RB2 on terminal block TB3: When a contact closure is made, the control will use FIG. 13 ­ REGEN TO STOP regenerative braking to bring the motor to a rapid stop. In the forward direction the rate of braking can be slowed by increasing the setting of the reverse acceleration trimpot (REV ACC). The rate of braking can be made faster by decreasing the setting of the REV ACC trimpot to its full CCW position. More rapid braking, when required, can be accomplished by increasing the setting of the reverse current limit trimpot (REV CL). [. . . ] Be sure control is in forward direction for FWD CL trimpot adjustment and likewise with REV CL. Do not leave motor shaft locked for more than 2 ­ 3 seconds to prevent motor damage. Adjusting the CL above 150% of motor rating can cause overheating and demagnetization of some PM motors. IR Compensation (IR Comp) ­ The IR Comp is used to stabilize motor speed under varying loads.
