11.1 Parameters to change in the Drive Group (skip if section 10 completed)
Press left/right to find 0.0 then up/down to find parameter number
The parameters described in Section 4 enable
Run/Stop operation via the red and green
buttons on the Inverter.
Section 10 explains how to enable remote
Run/Stop via a switch instead.
This section extends the functionality added in
section 10 to include Run Forward/ Reverse as
well as Stop.
Important: P1 and P2 refer to the P1 / P2 I/O
terminals NOT P1 / P2 power terminals.
11.2 Connecting the Switch
Digital Inputs
A wiring diagram is shown in the illustration
opposite. The switch used is a DPDT centre off
type.
The CM terminal provides a 24V DC output as
described in section 10.
When the switch is moved to the “F” (Forward)
position, the circuit between P1 and CM is
completed and the motor will turn forwards as
described in section 10.
In addition, when the switch is moved to the “R”
(Reverse) position, the circuit between P2 and
CM is completed and the motor will turn in
reverse.
Returning the switch to position “0" (off) will
stop the motor.
This behaviour uses two .
If both P1 and P2 receive 24V signals, the
motor will stop.
Any 24V DC signal from an external source
such as a PLC connected to P1 or P2 will
cause the Inverter to run forwards or
backwards.
Use shielded SY cable between the switch and
Inverter and ensure that the cable screen is
earthed as described in section 10.
