Remedy:
Program Continuation:
300750
Parameters:
1-584
Conditions:
The condition for the factor load system to motor system is: µm_to_incr <= 65535
The condition for the factor motor system to load system is: incr_to_µm <= 1
with µm_to_incr = 1 / incr_to_µm
Formula for rotary axis:
The following applies for rotary motor encoder and rotary axis:
incr_to_µm(n) = (MD1321 SAFE_ ENC_ GEAR_ DENOM(n) / (MD1322 SAFE_ ENC_
NUMERA(n)) * incr_to_µm_rot_rotax
with n = 0 ... 7 (gear stage) and
incr_to_µm_rot_rotax = (360000 / 8192) * (1 / MD1318 SAFE_ENC_RESOL)
• MD 1318 SAFE_ENC_RESOL (number of encoder lines 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 rotary motor encoder and linear axis:
incr_to_µm(n) = (MD1321 SAFE_ ENC_ GEAR_ DENOM(n) / (MD1322 SAFE_ ENC_
NUMERA(n)) * incr_to_µm_rot_lin
incr_to_µm_rot_lin = (1000 / 8192) * (1 / MD1318 SAFE_ENC_RESOL) * MD1320
SAFE_ENC_GEAR_PITCH
Explanations:
• MD 1318 SAFE_ENC_RESOL (number of encoder lines 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)
Request: During boot-up of the control.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
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 neces-
sary.
• MD 1317 SAFE_ENC_GRID_POINT_DIST Grid division linear scale (for linear encoder)
• MD 1318 SAFE_ENC_RESOL Encoder marks 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 determined via MD 1302:
$MD_SAFE_IS_ROT_AX.
