MD 1318 SAFE_ENC_RESOL (number of encoder pulses per revolution)
• MD 1321 SAFE_ENC_GEAR_DENOM[n] (encoder/load gear denominator)
• MD 1322 SAFE_ENC_GEAR_NUMERA[n] (encoder/load gear numerator)
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
Explanation:
• MD 1318 SAFE_ENC_RESOL (number of encoder pulses per revolution)
• MD 1320 SAFE_ENC_GEAR_PITCH (spindle pitch)
• MD 1321 SAFE_ENC_GEAR_DENOM[n] (encoder/load gear denominator)
• MD 1322 SAFE_ENC_GEAR_NUMERA[n] (encoder/load gear numerator)
• n = 0 ... 7 (gear stage)
Interrogation: When the control runs-up.

Remedy Please inform the authorized personnel/service department. Check the
following safety-relevant MDs depending on the motor encoder type and axis
type and correct, if necessary.
• MD 1317 SAFE_ENC_GRID_POINT_DIST Grid division, linear scale (for
linear encoder)
• MD 1318 SAFE_ENC_RESOL Encoder pulses per revolution (for rotary
encoder)
• MD 1318 SAFE_ENC_RESOL
• MD 1320 SAFE_ENC_GEAR_PITCH (for rotary encoder and linear axis)
• MD 1321 SAFE_ENC_GEAR_DENOM
• MD 1322 SAFE_ENC_GEAR_NUMERA (when using a gear)
• The motor encoder type and the axis type are specified using MD 1302
SAFE_IS_ROT_AX
Program continuation Power-down the control and power-up again.
300776 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DRIVE_READY are withdrawn.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DRIVE_READY are withdrawn.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.
