• 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 neces-
sary.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 drive %2 illegal current during rotor position identification
%1 = NC axis number
%2 = Drive number
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)
- 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.
Please inform the authorized personnel/service department. Check MD 1019 with rotor
position identification active and, if necessary, reduce the setting.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 drive %2 maximum permissible motor temperature exceeded
%1 = NC axis number
%2 = Drive number
The motor temperature (measured via the temperature sensor KTY 84 and fed to the
module through the motor encoder cable) has exceeded the temperature limit in drive MD
1607: $MD_MOTOR_TEMP_SHUTDOWN_LIMIT (motor temperature shutdown limit).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- 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.
Please inform the authorized personnel/service department.
• Motor overloaded.
• Check the motor data. Possibly the machine current was too high as a result of incorrect
motor data.
• Check the temperature sensor (2nd sensor possible with MSD).
• Check the motor encoder cable.
• Motor encoder defective.
• Check the motor fan.
• Check the acceleration.
