Axis %1 drive %2 number of encoder marks of measuring system invalid
%1 = NC axis number
%2 = Drive number
The number of encoder marks of the motor measuring system in the drive MD 1005:
$MD_ENC_RESOL_MOTOR (number of encoder marks of the motor measuring system)
is zero or greater than the maximum input limit.
- NC not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. Match the number of
encoder marks of the motor measuring system in drive MD 1005: ENC_RESOL_MOTOR
(number of encoder marks of the motor measuring system) to the encoder in use. (Default
setting for motor measuring system: (Default setting for motor measuring system: 2048
incr./rev.).
Switch control OFF - ON.
Axis %1 drive %2 voltage constant is zero
%1 = NC axis number
%2 = Drive number
The value in drive MD 1114: $MD_EMF_VOLTAGE is set to zero.
- NC not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department.
For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
For third-party motors: Check and, if necessary, refer to the motor data sheet to correct
MD 1114: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current).
Switch control OFF - ON.
Axis %1 drive %2 reactance less than or equal to zero
%1 = NC axis number
%2 = Drive number
The value in MD 1139: $MD_STATOR_LEAKAGE_REACTANCE (stator leakage reac-
tance) or MD 1140: $MD_ROTOR_LEAKAGE_REACTANCE (rotor leakage reactance) or
MD 1141: $MD_MAGNETIZING_REACTANCE (magnetizing reactance) is less than or
equal to zero.
- NC not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
