• n = 0 ... 7 (gear stage)
Request: During boot-up of the control.
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: 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.
Program Con- Switch control OFF - ON.
tinuation:
300750
Axis %1 drive %2 parameterization error in speed control adaption
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The upper adaptation speed MD 1412: $MD_SPEEDCTRL_ADAPTSPEED_2 (upper
adaption speed) is less than the lower adaptation speed MD 1411:
$MD_SPEEDCTRL_ADAPTSPEED_1 (lower adaption speed).
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Please inform the authorized personnel/service department.
$MD_SPEEDCTRL_ADAPTSPEED_2 (upper adaption speed) and MD 1411:
$MD_SPEEDCTRL_ADAPTSPEED_1 (lower adaption speed).
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
300751
Axis %1 drive %2 speed control gain too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The proportional gain of the speed controller MD 1407: $MD_SPEEDCTRL_GAIN_1 (P
gain of speed controller) or MD 1408: $MD_SPEEDCTRL_GAIN_2 (P gain of upper
adaption speed) has been set too high.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
