Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 drive %2 generator mode: Motion at rotor position identification
%1 = NC axis number
%2 = Drive number
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).
- Mode group not ready.
- Channel not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
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 or increase MD1020:
$MD_MAX_TURN_ROTORPOS_IDENT (maximum rotation of the rotor position identi-
fication).
• Brake the motor during the identification.
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)
