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.
- 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.
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
• Motor has become unstable because motor data grossly wrong
• Current limit is too low for the motor (0.9 * MD 1238 * MD 1103 < MD 1136)
• Power section too small
- 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. Remedy the cause.
• Modify MD 1238: $MD_CURRENT_LIMIT (current limit)
• Modify MD 1103: $MD_MOTOR_NOMINAL_CURRENT (motor nominal current)
• Modify MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current)
• Use greater power section.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
