4.7. Control Terminal Wiring
All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.
Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.
Maximum control terminal tightening torque is 0.5Nm.
Control Cable entry conductor size: 0.05 – 2.5mm2 / 30 – 12 AWG.
4.8. Using the REV/0/FWD Selector Switch (Switched Version Only)
By adjusting the parameter settings the Optidrive can be configured for multiple applications and not just for Forward or Reverse.
This could typically be for Hand/Off/Auto applications (also known and Local/Remote) for HVAC and pumping industries.
The integrated switch operates in parallel with drive terminal 2 (T2) and terminal 3 (T3) as digital input 1 and digital input 2.
By default, the integrated switch is enabled.
If required, the built in control switch may be disabled using the following method:
1) Set correct value in P-14 to enable advanced parameter access, e.g. 201
2) Go to “P-00” and make sure drive is in stop condition (not running, not tripped).
3) Press and hold “STOP” button for about 1s, drive will show “Lc-OFF” or “Lc-On” message.
4) Use “UP” or “DOWN” key to select the option: “Lc-OFF” means integrated switches are enabled. “Lc-On” means the switches are
locked/disabled.
5) Press the “STOP” button again to exit.
