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 add the RS485 termination jumper to the B hoist VFD
as shown on the EZCOM circuit wiring example.
Add the tandem activation circuit to digital input 6 on each VFD as shown in the EZCOM circuit wiring example on the
3
next page.
Power up the VFD's together at the same time and verify the communication is not disconnected by using the monitor
4
parameter db-08. If The value in db-08 = 9999 then troubleshooting is required.
5 Operate the hoists in tandem and individually and verify correct operation.
