ACH550 E-Clipse Bypass

3018

MAX CYCLE 

FAULT

Supervisory Mode only. 

Declared if bypass 

contactor is closed by 

supervisory control 16 

times within a 1 hour 

period.

High and low levels of 

hysteresis band are too 

tight 

Check parameters 

3202-3205. Increase 

time delays on 

parameters 3204 and 

3205

3019

DRIVE LINK FAULT Supervisory Mode 

Only. Fault generated if 

RS-485 link between 

drive and bypass stops 

communicating.

Bad cable/connection 

between drive and 

bypass.
Communication 

improperly set in drive 

Parameter 9802. 

Application Macro 

improperly set in drive 

parameter 9902.

Proper seating of cable 

in drive and 

RBCU(connector J3)
Check drive parameter 

9802 (Modbus) and 

9902 (E-Clipse)
Check drive Group 53 
Follow DriveLink 

recovery procedure

PHASE SEQ

Sequence of 3 phase 

voltage input is such 

that bypass operation 

will result in motor 

rotation opposite of 

drive forward operation.

Phase sequence 

unknown at time of 

wiring

Swap any two of the 

three input wires to the 

bypass unit

3021

PH A CURR FBK

Fault is generated 

when current in Phase 

A  is detected and the 

bypass contactor is 

open

Loose CT connection
Bad RBCU
Bad CT

Check J2 connector for 

proper seating
Check connector on 

Current Assembly
Replace RBCU
