Optional module functions
External relay
The P6-21:Relay output 3 and 4 parameter controls the function for relay 3 and 4. Relay 5
is always closed when the drive runs.
External I/O controller
To put the drive in external I/O control mode, close extended digital input 3. In external
I/O control mode, the drive does not respond to the keypad buttons On, Off, Hand or
Auto. The drive can now be put in two modes. By enabling extended digital input 1, the
drive goes into auto mode and starts when the start level is reached. Auto mode
corresponds to pushing the buttons auto and then On.
By enabling extended digital input 2, the drive starts at maximum speed. This setting
corresponds to pushing the buttons Hand and then On.
If both extended digital input 1 and 2 are opened or closed, then the drive does not start.
To switch back to the drive keypad control, open extended digital input 3.
The module has a built-in relay that is configured as relay 3 in the P6-21:Relay output 3
and 4 parameter.
