Formula for linear axis:
The following applies for a rotary motor encoder and linear axis:
inkr_to_µm(n) = (MD1321 SAFE_ ENC_ GEAR_ DENOM(n) / (MD1322 SAFE_
ENC_NUMERA(n)) * inkr_to_µm_rot_lin
inkr_to_µm_rot_lin = (1000 / 8192) * (1 / MD1318 SAFE_ENC_RESOL) *
MD1320 SAFE_ENC_GEAR_PITCH

Axis %1, drive %2 Measuring circuit monitoring must be active
Parameter %1 = NC axis number
%2 = drive number
Explanation For FD:
The control is inhibited, the motor is braked, SIMODRIVE_READY and
DRIVE_READY are withdrawn.
For MSD:
The pulses are cancelled, the motor coasts down, SIMODRIVE_READY and
DRIVE_READY are withdrawn.
Note: The response (FD, MSD) can be configured using 611D-MD 1613.0.
Interrogation: When the control runs-up and cyclic.
For active Safety Integrated (MD 1301 <> 0:
$MD_SAFE_FUNCTION_ENABLE (enable safe functions)), the measuring
circuit monitoring of the motor (incremental) must be activated via MD 1600:
$MD_ALARM_MASK_POWER_ON (alarms that can be suppressed (power on)
bit 4.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
NC stop for alarm
