20097 Axis %1 incorrect travel direction brake test
Parameters: %1 = Axis name, spindle number
Definitions: Due to the selected travel direction, the brake test for the current load torque is performed with an
incorrect torque.
Reaction: Alarm display.
Remedy: - Perform the brake test for the other travel direction
- Adjust drive MD 1192 better to the current weight ratio. The alarm will occur only if the current torque
deviates from MD 1192 by more than 5% when the brake is released.
- Activate the automatic determination of the load torque at the beginning of the brake test via MD
$MA_SAFE_BRAKETEST_CONTROL, Bit 0 = 1.
Program Clear alarm with the Delete key or NC START.
Continuation:
20100 Channel %1: invalid configuration for digitizing
Parameters: %1 = Channel number
Definitions: - The digitizing function expects the definition of 3 geometry axes in the channel.
- At the available baud rate for a transmission of the actual positions and setpoint velocities between
the NC and the digitizing device, the interpolation cycle must be set to a minimum of 5ms.
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform authorized personnel / the service department.
- Define 3 geometry axes for the digitizing channel by means of machine data.
- Use an interpolation cycle greater than 5ms.
Program Switch control OFF - ON.
Continuation:
20101 Timeout during initialization of communication with the digitizer
Definitions: The attempt to synchronize the communications link to the digitizing unit and to transfer the machine
parameters was aborted after the preset timeout limit of 15 seconds was exceeded.
Reaction: Interface signals are set.
Alarm display.
Remedy: Check the connection to the digitizing unit (RS422 cable, supply voltage) and whether the digitizing
unit is switched on.
Program Clear alarm with the Delete key or NC START.
Continuation:
20102 Channel %1: No or invalid trafo at digitizing active
Parameters: %1 = Channel number
Definitions: Prerequisite for the 3+2 axis digitizing is an active kinematic transformation. Permitted transformations
are the general 5-axis transformation and the universal inclinable head.
Reaction: Interface signals are set.
Alarm display.
Remedy: - Before digitizing, activate a permitted transformation.
- Select 3-axis mode for digitizing via machine data.
Program Clear alarm with the Delete key or NC START.
