- 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 rota-
tion 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 nec-
essary.
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
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)
Reactions: - 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 Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
300613
Axis %1 drive %2 maximum permissible motor temperature exceeded
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 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).
Reactions: - 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.
