APPENDIX 5 Processing Times of the Motion CPU

Operation cycle
When "WAIT ON/OFF +
Servo program
Motion control step" is
start processing
used.
(Note-1)
time
When only Motion control
step is used.
Speed change response
Simultaneous start processing time
Time from PLC ready flag (M2000) ON to
PCPU ready flag (M9074) ON
(Note-1) : FEED instruction varies greatly depending on the condition (whether other axes are operating or being stopped).
(Note-2) : This processing time varies depending on the simultaneous start command. Use this time merely for reference.
(Note-3) : MR-H BN does not support an operation cycle of 0.88[ms]. If the MR-H-BN is set in the system settings,
1.77[ms] is used as the real operation cycle even when 0.88[ms] is set.
The processing time of each signal and each instruction for positioning control in the
Multiple CPU system is shown below.
(1) Motion operation cycle [ms] (Default)
Number of setting axes (SV22)
Operation cycle [ms]
(2) CPU processing time [ms]
0.88[ms]
1.1 to 1.6
1.8 to 2.3
1.2 to 2.0
(Note-2)
1.7 to 2.5
(3) Virtual servomotor axis/synchronous encoder axis operation cycle
[ms] (Default)
Number of setting axes (SV22)
Virtual servomotor [ms]
Synchronous encoder [ms]
