SIMOVERT MASTERDRIVES Operating Instructions
Counter-measure
- Measure intake air or ambient temperature.
- Observe the derating curves at theta >45°C
(Compact PLUS) or 40°C.
Check
- Whether the fan -E1 is connected and is
rotating in the correct direction.
-The air intake and discharge openings for
blockage.
- The temperature sensor at -X30.
- r833 indicates the maximum converter
temperature of all existing measuring points
(Compact/chassis type unit).
- r833.01 indicates the actual converter
temperature (Compact PLUS type).
Check the motor (load, ventilation, etc.). The
current temperature can be read in r009 Motor
Tmp.
Check the KTY84 input at connector
-X103:29,30, or -X104:29,30 (Compact PLUS
type) for short-circuit.
Lock the motor.
Check:
- P72 Rtd Drive Amps
- MLFB P70
- P128 Imax
- r010 Drive Utilizat
Motor load cycle is exceeded!
Check the parameters:
P382 Motor Cooling
P383 Mot Tmp T1
P384 Mot Load Limits
P804 Overspeed Hys plus
P452 n/f(max, FWD Spd) or
P453 n/f(max, REV Spd) has been exceeded
Increase the parameter for the maximum
frequencies or reduce the regenerative load.
Check
- whether an excessive torque requirement is
present
- whether the motor has been dimensioned too
small.
Increase values P792 Perm Deviation Frq/
set/actual DevSpeed and P794 Deviation Time
Check whether cable(s) to the corresponding
digital input(s) P572 Src FWD Spd / P571 Src
REV Spd is (are) interrupted or released
