EZCOM SETUP GUIDE

Step
Configure the VFD's parameters using the EZCOM parameter chart. Most of the parameters should already be
1
configured and only the ones highlighted in yellow should need to be changed.
Power down both VFD's and connect the 2-wire shielded cable to the corresponding SN & SP terminals as shown in
2 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.
Add the tandem activation circuit to digital input EA on each VFD as shown in the EZCOM circuit wiring example on
3
the next page.
Power up the VFD's together at the same time and verify the communication is not disconnected by using the
4
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.
