(J2-20) pins open Verify TS+ (J2-19) and TS-
(J2-20) connections for conti-
nuity.
Motor thermostat trips due
to:
High motor ambient temper-
ature, and/or
Excessive RMS torque Operate within (not above) the
continuous torque rating for
the ambient temperature (40°C
maximum).
Lower ambient temperature.
IPM Fault 05 Motor cables shorted Verify continuity of motor
power cable and connector.
Motor winding shorted inter-
nally Check for short on R,S,T and
Gnd windings of the motor.
Drive temperature too high Check for clogged or defective
fan.
Ensure cooling is not restricted
by insufficient space around
the unit.
Operation above continuous
power rating Verify ambient temperature is
not too high (above 60° C).
Operate within the continuous
power rating.
