300740 Axis %1 drive %2 measuring system used several times
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The NC has assigned the direct measuring system to a measuring system output which is already
used by another direct measuring system. This error can only occur with the 810D!
Reaction: 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.
Remedy: Please inform the authorized personnel/service department. Check the configuration of the direct
measuring system. See NC-MD 30220: $MA_ENC_MODULE_NR and NC-MD 30230:
$MA_ENC_INPUT_NR.
Program
Continuation:
Switch control OFF - ON.
300741 Axis %1 drive %2 asynchronous mode: feedforward control gain out of
range
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: If motor inertia and motor nominal torque have been selected unfavorably, the asynchronous motor
feedforward control gain is beyond the range of the internal number format.
Reaction: 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.
Remedy: Please inform the authorized personnel/service department.
- Operation without encoder: Reduce the number of encoder lines in MD 1005:
$MD_ENC_RESOL_MOTOR (encoder resolution for motor measuring system), since this has an
impact on the internal number format. Optional/additional measure: see operation with encoder
- Operation with encoder: Reduce speed controller cycle MD 1001:
$MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle).
Program
Continuation:
Switch control OFF - ON.
300742 Axis %1 drive %2 voltage/frequency mode: converter frequency invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Only converter frequencies (MD 1100: $MD_PWM_FREQUENCY (pulse width modulation
frequency)) of 4 kHz or 8 kHz are permissible in V/f mode (selected via MD 1014:
$MD_UF_MODE_ENABLE).
Reaction: 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.
Remedy: Please inform the authorized personnel/service department. Check and, if necessary, correct the
torque adaptation factor MD 1100: $MD_PWM_FREQUENCY (pulse width modulation frequency) or
remedy the problem by deselecting V/f mode MD 1014: $MD_UF_MODE_ENABLE.
Program
Continuation:
Switch control OFF - ON.
