• Fan failure
• Observance of the minimum clearance over and under the power section (see Planning
Guide)
Switch control OFF - ON.
Axis %1 drive %2 motor encoder is not adjusted
%1 = NC axis number
%2 = Drive number
The stored serial number of the encoder on a linear motor encoder with an EnDat inter-
face does not match the number of the active encoder. It is therefore assumed that the
encoder has not been started up with the motor in question before or has not been
adapted to the motor.
- 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.
For 1FN3 linear motors: Measure the rotor position offset to the EMF of the U_R phase
and add it as commutation angle offset to MD 1016
$MD_COMMUTATION_ANGLE_OFFSET. Then set MD 1017
$STARTUP_ASSISTANCE to "-1" to store the serial number of the Endat encoder. Then
save the bootfiles and execute an NCK Reset. Otherwise: To determine the commutation
angle offset in MD 1016, initiate the rotor position identifier via MD 1017 = 1. After the
error has been acknowledged, the identification is carried out.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 drive %2 motor change not valid
%1 = NC axis number
%2 = Drive number
An attempt was made to switch over to a motor data record that is not parameterized.
- 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.
Parameterize the motor data record selected or switch over to another motor.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 drive %2 flux controller at limit
%1 = NC axis number
%2 = Drive number
The specified flux setpoint cannot be achieved even though the maximum current has
been provided.
Causes:
• Incorrect motor data (replacement circuit diagram data)
• Motor data and motor connection type (star/delta) do not match
