Switch control OFF - ON.
Axis %1 drive %2 monitoring cycle time MD 1300 invalid
%1 = NC axis number
%2 = Drive number
Check and, if necessary, correct MD 1300: $MD_SAFETY_CYCLE_TIME (monitoring
cycle) has not been set as a multiple of the NC position control cycle.
Request: During boot-up of the control.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. Set the monitoring cycle via
MD 1300 to n * NC position control cycle, n must be >= 1.
Switch control OFF - ON.
Axis %1 drive %2 monitoring cycle times of both axes differ
%1 = NC axis number
%2 = Drive number
The monitoring cycles set in MD 1300: $MD_SAFETY_CYCLE_TIME (monitoring cycle)
for the two axes of a 2-axis module are not identical.
Request: During boot-up of the control.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. Check and, if necessary, cor-
rect MD 1300: $MD_SAFETY_CYCLE_TIME (monitoring cycle) on all drives of the mod-
ule.
Switch control OFF - ON.
Axis %1 drive %2 conversion factor between motor and load too large
%1 = NC axis number
%2 = Drive number
The conversion factor from the motor system [increments] to the load system [µm/mdeg]
is larger than 1 or the factor which converts the load system to the motor system is larger
than 65535.
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)
