User manual BENSHAW RSI (S-SERIES)

[. . . ] This inverter contains high voltage which can cause electric shock resulting in personal injury or loss of life. 2. Be sure all AC power is removed from the inverter before servicing. 3. Wait at least 3 minutes after turning off the AC power for the bus capacitor to discharge. Make sure to check the Charge LED on the PCB. 4. [. . . ] Set the speeds and parameters in Auto [12]-[32]. Remember that in Auto B, contact closures are needed to activate any of the speed or direction changes. Example) Set AUTO in FUN [01]. Set each frequency, transient time, steady time, and drive direction needed. Set-up terminals P1, P2, P3 as input terminals as shown below.

FUN 60 ­ Acceleration Time during Speed Search Mode FUN 61 ­ Deceleration Time during Speed Search Mode I/O 01 to I/O 06 ­ Multifunction Input Selection (select SS) These acceleration and deceleration times are used when the speed search mode is selected via one of the multifunction input terminals (P1 through P6). Also, refer to speed search later in this chapter.

When the Auto mode is selected, the drive uses this counter to determine when to initiate various run patterns that are pre-programmed in the Auto group. This mode can also be used for grouping different drive commands together. AUT 01: Auto Mode [AUTO A] Mode will allow the drive to operate automatically by following its pre-programmed time schedule. According to this time schedule, 8 different steps of frequency commands, directions of motor, run time, and transient times can be initiated with only a single multifunction input contact closure (I/O 01 to I/O 06). [AUTO B] Mode can be also used to program up to 8 different steps as in Auto A. However, to switch from one step to another, an external contact closure to one of the multifunction-input terminals is required. AUT 01 Auto mode Auto A AUT 02: Sequence Select (Number of Sequence Selection) The RSi-S can have total of 7 whole sequences (Batches) in Auto mode. Each sequence can have up to 8 different steps (each step includes separate frequency commands, directions of motor, run time, and transient times). With this parameter, the operator can select the number of sequences to program. AUT 02 Seq select 1 93 Chapter 6 - Advanced Features · Table 2.

The value X depends on the value of AUT 02. For example, if the AUT 02 is programmed to be 3, then the display will read Steps (Seq 3). If the total number of steps for the sequence 3 is 7, then AUT03 should be set to 7.
