- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department.
Rectify error by selecting pure AM mode (MD1465 = 0) or by deselecting the AM-con-
trolled mode (MD1466 < MD1465).
• Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
• Modify MD 1466: $MD_SWITCH_SPD_OPEN_LOOP_AM (switchover speed closed-
loop/open-loop control AM)
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 fixed link voltage of axes differ
%1 = NC axis number
%2 = Drive number
An unequal fixed voltage MD1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage)
has been found for axes of a drive module. Since a fixed voltage <> 0 replaces the mea-
sured DC link voltage value, but the DC link voltage value is measured only once for all
axes of a drive module, the fixed voltage must be identical on all module axes before it is
accepted.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. Set the same fixed voltage
(MD 1161) on all module axes. $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage) has
been found for axes of a drive module.
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 measuring circuit monitoring must be active
%1 = NC axis number
%2 = Drive number
On FDD:
The control is disabled, the motor is decelerated, SIMODRIVE_READY and
DRIVE_READY are canceled.
On MSD:
Pulse delete, motor coasts, SIMODRIVE_READY and DRIVE_READY are canceled.
Note: The reaction (FDD, MSD) can be configured via 611D-MD 1613.0.
Request: During boot-up of the control and cyclically.
With active Safety Integrated (MD 1301 <> 0: $MD_SAFE_FUNCTION_ENABLE (safe
functions enable)), the measuring circuit monitoring of the motor (incremental) must be
activated via MD 1600: $MD_ALARM_MASK_POWER_ON (concealable alarms (Power
On) bit 4.
