(6) Capacitor fuse blown
F_C
A fuse is provided in the capacitor unit to prevent damage expansion at short-circuit occurrence. A blown
fuse is detected by the mocroswitch.
(7) Output contactor open
ACSW (optional) (TMdrive-30)
When the output contactor that should be on is off, an ACSW error is detected.
(8) Output open
AC_NL (TMdrive-30)
AC_NL is detected when the output open state is detected.
(9) CPU error
CPU_A, CPU_M
An error is detected (by watchdog detection) in the microprocessor that performs control operation.
A CPU error in the circuit board is detected by hardware to protect CPU.
(10) Transmission error
TL_F1 ~ TL_F4
An error is detected in main unit transmission and transmission between drives.
(11) Pre-charge fuse blown
F_PRE (TMdrive-P30)
A fuse is provided on the pre-charge circuit to prevent damage expansion at short-circuit accident
occurrence. A blown fuse is detected by the microswitch.
(12) Grounding fuse blown
F_GND (TMdrive-P30)
A fuse is provided on the grounding circuit to prevent damage expansion at grounding accident occurrence.
A blown fuse is detected by the microswitch.
2.3.11.5 Protection Associated with Motor and Break (TMdrive-30)
(1) Motor overheat
M_OH,M_OH_A
When a temperature sensor is provided (optional) for the motor, temperature is detected to protect the
motor.
The standard setting is $CP_MOTOR_OH = 155
°
C.
An M_OH_A alarm is activated at 10
°
C lower (fixed) than this setting value.
(2) Motor temperature detector fault MTMP_S
When the temperature of the motor temperature sensor above exceeds 200
°
C (fixed value), a sensor fault
is assumed and MTMP_S is detected.
(3) Motor cooling fan stop
M_FN,M_FN_T
If the motor cooling fun circuit is located outside, the operation signal of the cooling fan circuit is connected
to the inverter. This enables the motor cooling fan interlock to be set.
It is also possible to output an alarm to outside by an M_FN signal and stop the equipment when an
M_FN_T signal is activated after an elapse of time specified by the TIME_MFAN timer.
The standard setting is TIME_MFAN = 0.0 (s).
(4) Electromagnetic brake energizing circuit fault
BR_F
When an electromagnetic brake is provided optionally, brake energizing circuit fault is detected.
