Overview of Alarms
NCK alarms
NC Stop on alarm.
Remedy: Check and change the specified MD. Allow the checksum to be recalculated. Re-accept safety func-
tions.
Program Con- Switch control OFF - ON.
tinuation:
27034 Parameterization of MD %1[%2] invalid.
Parameters: %1 = MD identifier
%2 = Machine data index
Definitions: The parameterization of machine data %1 is incorrect. This alarm occurs in the following contexts:
- An invalid value has been set for MD $MN_SAFE_ALARM_SUPPRESS_LEVEL.
- An invalid value has been set for MD $MN_SAFE_RDP_CONNECTION_NR.
- An invalid value has been set for MD $MN_SAFE_SDP_CONNECTION_NR.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check and correct the specified machine data.
Program Con- Switch control OFF - ON.
tinuation:
27035 Axis %1 new hardware component, confirmation and functional test
required.
Parameters: %1 = Axis number
Definitions: The IDs for the corresponding hardware components (encoder, motor module)
read out by the drive do not match the NCK parameterization.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: The following has to be done if the alarm occurs during the start-up:
- Confirm the checksum SAFE_ACT_CHECKSUM[1] (key switch position 3 or password has to be
entered). Continue the start-up.
The following has to be done if the alarm occurs after an encoder module or a DRIVE-CLiQ motor has
been replaced:
- In the Diagnostics operating area, confirm the hardware checksum with softkey in
SAFE_ACT_CHECKSUM[1] (key switch position 3 or password has to be entered)
- Readjust the actual value encoder.
- Check the SI actual value acquisition: velocities, traversing direction, absolute position (set user
acknowledgement if necessary)
- Document the new checksum value in SAFE_ACT_CHECKSUM[1] and the last entry in the change
history in MD SAFE_CONFIG_CHANGE_DATE[0]
- Document the hardware and software version data of the new component.
Program Con- Switch control OFF - ON.
tinuation:
27036 Axis %1 encoder parameterization MD %2[%3] has been adjusted.
Parameters: %1 = Axis number
%2 = MD identifier
%3 = Machine data index
Definitions: Encoder parameterization of the encoder read out by the drive for the SI monitoring functions
does not match NCK parameterization in the displayed MD. The relevant NCK MD has been adjusted.
