3.3.2 Drive Module
Resolver not ok.
Indicated by: LED DRVF, LED RF (Resolver Fault), optoisolated output DRIVE OK, bit B of
the FA string (see FA command).
Set condition: when the resolver is not connected or in short circuit at the power up, when
the resolver fails or is disconnected during running.
Effect: the drive inhibit torque of all axes of the module.
Reset condition: if the condition is not present anymore, reset button on drive or send pulse
to REM RESET.
Motor over temperature.
Indicated by: LED DRVF, LED OVT, optoisolated outputs DRIVE OK and MOTOR OK, bit C
of the FA string (see FA command).
Set condition: when a limit temperature is reached inside the motor.
Effect: the drive inhibit torque of all axes of the module.
Reset condition: if the condition is not present anymore, reset button on drive or send pulse
to REM RESET.
Notes: the fault information via LEDS and opto is reset when the motor temperature goes
down the limit, while the drive is disabled until the reset condition has been met.
Short on axis.
Indicated by: LED DRVF, LED SHRT CCT, optoisolated output DRIVE OK, bit D of the FA
string (see FA command).
Set condition: when a short circuit is detected between the motor phases, phase and ground,
phase and HV.
Effect: the drive inhibit torque of all axes of the module.
Reset condition: if the condition is not present anymore, power off and on the aux power
supply.
