Modify drive machine data
• Modify MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator
axis) or
• Modify MD 1632: $MD_LINK_VOLTAGE_GEN_HYST (voltage range for generator
control) or
• Modify MD 1633: $MD_LINK_VOLTAGE_GEN_OFF (voltage range for generator con-
trol) or
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 generator mode: response voltage > monitoring threshold
%1 = NC axis number
%2 = Drive number
The value in MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator
axis) is greater than MD1630: $MD_LINK_VOLTAGE_MON_THRESHOLD (response
threshold for DC link monitoring).

Axis %1 drive %2 generator mode: emergency retraction speed > max. motor
speed
%1 = NC axis number
%2 = Drive number
The value entered for the emergency retraction speed in MD1639:
$MD_RETRACT_SPEED (emergency retraction speed) is greater than MD1146:
$MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed).
