EZCOM SETUP GUIDE
1
Configure the VFD’s parameters using the EZCOM parameter chart. Most of the parameters should already be
configured and only the ones highlighted in yellow should need to be changed.
2
Power down both VFD’s and connect the 2-wire shielded cable to the corresponding SN & SP terminals as shown in
the EZCOM circuit wiring example on the next page. Be sure to enable the RS485 termination resistor on B hoist VFD
as shown on the EZCOM circuit wiring example.
3
Add the tandem activation circuit to digital input EA on each VFD as shown in the EZCOM circuit wiring example on
the next page.
4
Power up the VFD’s together at the same time and verify the communication is not disconnected by using the
monitor parameter d025. If The value in d025 = 9999 then troubleshooting is required.
5 Operate the hoists / trolley in tandem and individually and verify correct operation.
