VSD Emergency Stop Setup
- Set b1-07 = 0 (default “Decelerate to Stop”)
From the External Device, connect the Normally Closed wire with DI1 and Common with Common and then set:
- Set b3-00 = 44 (Emergency Stop)
- If the External Device is Normally Open, also set b3-25 = 1
*When the terminal becomes ON, the VSD stops within the shortest time. During the stop process, the current remains at the set current upper limit (to enable the VSD to stop in emergency state).
*When using a normal deceleration stoppage procedure and reducing the deceleration time to a very short time, a brake unit and/or resistor might be required to burn off the excess energy (not required for above Emergency Stop Procedure – only if stoppage time needs to be reduced even further than what is possible via the emergency stop).
- For VSDs more than 22KW, a brake unit and brake resistor is also needed.
- For VSDs up to 22kW a brake resistor is already built in, but an additional brake unit might be required depending on the application.
