Please inform the authorized personnel/service department. Provide better ventilation of
the drive modules, e.g. by means of:
• Greater air throughput in the switching cabinet, if necessary cool the ambient air of the
611D modules.
• Avoid numerous acceleration and deceleration operations in rapid sequence by modify-
ing the workpiece programming.
• Incorrect motor/power section dimensioning
• Excessive ambient temperature (see Planning Guide)
• Exceeding of the installation height (see Planning Guide)
• Excessive pulse frequency (see Planning Guide)
• Defective module
• Fan failure
• Observance of the minimum clearance over and under the power section (see Planning
Guide)
Switch control OFF - ON.
Axis %1, drive %2 DC link voltage too high
%1 = NC axis number
%2 = Drive number
The current DC link voltage in MD1701:$MD_LINK_VOLTAGE is larger than MD1163:
$MD_LINK_VOLTAGE_MAX and MD1165: $MD_DYN_MANAG_ENABLE is activated.
- 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.
Increase drive machine data
• MD 1163: $MD_LINK_VOLTAGE_MAX or deactivate
• MD 1165: $MD_DYN_MANAG_ENABLE.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
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.
- 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.
