Overview of Alarms
SIMODRIVE alarms
- The axis must move freely (e.g. motor not stalled).
- Reduce high axis friction (increase P1019)
Program Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
300611 Axis %1 drive %2 generator mode: Motion at rotor position identification
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: During the measurement, the motor has turned by more than the permissible value entered in
MD1020: $MD_MAX_TURN_ROTORPOS_IDENT (maximum rotation of the rotor position
identification). The rotation can be caused by switching on a rotating motor or by the identification
itself.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Please inform the authorized personnel/service department.
- If the rotation was caused by the identification itself, and if the error occurs repeatedly, then reduce
MD1019: $MD_CURRENT_ROTORPOS_IDENT (rotor position identification current) or increase
MD1020: $MD_MAX_TURN_ROTORPOS_IDENT (maximum rotation of the rotor position
identification).
- Rotor position identification with inductance: stall the motor during the identification
- Rotor position identification with movement: check the factor load mass/load moment of inertia
MD1076: $MD_FACTOR_MASS / $MD_FACTOR_INERTIA and increase if necessary.
Program Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
300612 Axis %1 drive %2 illegal current during rotor position identification
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 1. With rotor position identification active, the current was
>= 1.2 * 1.05 * INVERTER_MAX_CURRENT (MD 1107)
2. With rotor position definition active, the current was
>= MOTOR_MAX_CURRENT (MD 1104)
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Please inform the authorized personnel/service department. Check MD 1019 with rotor position
identification active and, if necessary, reduce the setting.
Program Clear alarm with the RESET key in all channels of this mode group. Restart part program.
