$MA_SAFE_STOP_VELO_TOL.
- 28. A value greater than 1000 mm/min was entered for a linear axis in MD $MA_SAFE_VELO_X.
- 29. A value greater than 1000 mm/min was entered for a linear axis in
$MA_SAFE_SLIP_VELO_TOL.
- 30. A value greater than the maximum settable encoder limit frequency for the safe operation of a
single-encoder system was set in MD $MA_SAFE_ENC_FREQ_LIMIT.
- 31. A value greater than 300kHz for a Performance-1 or Standard-2 control module was set in MD
$MA_SAFE_ENC_FREQ_LIMIT.
- 32. MD $MA_SAFE_EXT_PULSE_ENAB_OUTPUT was not or not correctly parameterized. A
parameterization of this MD is required if in MD $MA_SAFE_PULSE_ENABLE_OUTPUT, bit30 is set
to 1, i.e. internal pulse suppression is being used.
- 33. The MD $MN_SAFE_SPL_STOP_MODE has been parameterized to the value of 4 (Stop E)
without having enabled the external Stop E in all the axes with SI function enables (MD
$MA_SAFE_FUNCTION_ENABLE not equal to 0).
- 34. Testing the mechanical system of the brakes was enabled in MD $MA_FIXED_STOP_MODE
(bit1 = 1), without previously enabling the safe operation function for this axis in MD
$MA_SAFE_FUNCTION_ENABLE. Testing the mechanical system of the brakes is permitted only
with safety functions in this axis.
- 35. Illegal values have been parameterized in MD $MA_SAFE_VELO_STOP_MODE or MD
$MA_SAFE_VELO_STOP_REACTION.
- 36. In MD $MA_SAFE_FUNCTION_ENABLE, the cam synchronization was activated via bit7
without enabling any cams via bit8...bit15 or via $MA_SAFE_CAM_ENABLE.
- 37. The cam is enabled both via $MA_SAFE_FUNCTION_ENABLE and via
$MA_SAFE_CAM_ENABLE
- 38. In MD $MA_SAFE_DRIVE_PS_ADDRESS an invalid value was parameterized or the same
address was assigned for several axes.
- 39. The internal default of MD $MA_SAFE_ENC_PULSE_SHIFT from drive parameterization could
not be executed, as some values outside the specified range would have to be defaulted in this case.
Adjust the encoder parameterization in the drive.
- 40. The MD $MA_SAFE_VELO_OVR_FACTOR was parameterized with digits behind the decimal
point.
- 41. The logical start addresses configured in the hardware configuration and in MD
$MA_SAFE_CTRLOUT_MODULE_NR, $MN_SAFE_DRIVE_LOGIC_ADDRESS are not the same
or the slot addressed by it has the wrong length.
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 change the specified MD. Allow the checksum to be recalculated. Re-accept safety
functions.
Program Switch control OFF - ON.
Continuation:
27034 Parameterization of MD %1 invalid.
Parameters: %1 = MD identifier
Definitions: The parameterization of %1 is incorrect. This alarm occurs in the following context:
- an incorrect value was entered for MD $MN_SAFE_ALARM_SUPPRESS_LEVEL.
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 Switch control OFF - ON.
