$MA_SAFE_EXT_STOP_INPUT[0]) was parameterized inverted (bit31 = 1) or the SGE
"Deselect ext. Stop A" was not parameterized at the SPL interface $A_OUTSI.
• 25. The function "Save actual value with incremental encoder" is enabled via MD
$MA_ENC_REFP_STATE for the parameterizable incremental encoder, and a monitoring
function with absolute reference (SE/SN) is enabled via MD
$MA_SAFE_FUNCTION_ENABLE. It is not permissible to combine these functions.
• 26. A value greater than 1000 mm/min was entered for a linear axis in MD
$MA_SAFE_STANDSTILL_VELO_TOL.
• 27. A value greater than 20000 mm/min was entered for a linear axis in MD
$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 parameter-
ized. 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 parameter-
ization 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.
Reactions: - 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 Con- Switch control OFF - ON.
tinuation:
27034
Parameterization of MD %1 invalid.
Parameters: %1 = MD identifier
