Overview of Alarms
- 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: 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.
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
300605
Axis %1 drive %2 motor change not valid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: An attempt was made to switch over to a motor data record that is not parameterized.
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: Parameterize the motor data record selected or switch over to another motor.
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
300606
Axis %1 drive %2 flux controller at limit
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 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
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.
