Overview of Alarms
SIMODRIVE alarms
300778 Axis %1 drive %2 generator mode: converter frequency rotor position
identification
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: When selecting the rotor position identification (MD1011 bit 12 or bit 13) only converter frequencies
(MD1100) of 4 kHz/8 kHz are permissible.
- Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM)
- Modify MD 1100: $MD_PWM_FREQUENCY (pulse width modulation frequency)
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: NC 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.
Change the converter frequency (MD 1100) or deselect rotor position identification (MD1011 bit 12 or
bit 13).
- Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM)
- Modify MD 1100: $MD_PWM_FREQUENCY (pulse width modulation frequency)
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300779 Axis %1 drive %2 motor moment of inertia less than or equal to zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD 1117: $MD_MOTOR_INERTIA (motor moment of inertia) is less than or equal to
zero.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: NC 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.
- For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
- For MSD, configure "1st motor" first.
- For third-party motors: Enter a valid value in drive MD 1117: $MD_MOTOR_INERTIA (motor
moment of inertia).
Program Clear alarm with the RESET key in all channels. Restart part program.
