VSD Forward and Reverse Setup
To setup a Forward and Reverse Running function for a drive a 3-way Switch can be used (see image below for wiring) with the following parameter settings:
- Set b0-02 = 1 (Terminal Control) – This is to ensure the Start/Stop functions are triggered via the Terminal Controls.
- Set b3-00 = 1 (To set DI1 as the Forward Run terminal)
- Set b3-01 = 2 (To set DI2 as the Reverse Run terminal)
As another option (without using rocker switch), 2 separate On/Off switches can also be used as follows:
- Switch 1: Connect switch to DI1 and COM
- Switch 2: Connect switch to DI2 and COM
Set the following parameter settings:
- Set b0-02 = 1 (Terminal Control) – This is to ensure the Start/Stop functions are triggered via the Terminal Controls.
- Set b3-00 = 1 (To set DI1 as the Forward Run terminal)
- Set b3-01 = 2 (To set DI2 as the Reverse Run terminal)
- Set b3-13 = 2 (To set the Terminal Command Mode to Three-Line mode)
Based on these the drive will operate as follows:
- If Switch 1 is Off, the Drive will not Run the Motor (irrespective of the status of Switch 2)
- If Switch 1 is On and:
- Switch 2 is On: The Drive will Run the Motor in a FWD Direction
- Switch 2 is Off: The Drive will Run the Motor in a REV Direction
