Value Range
When servo torque function is selected using [Pr.358], output
frequency for generating servo torque increases to the creep
1 0.1 to 100 speed of [Pr.352] gradually according to the slope set in [Pr.362].
Although the operation becomes faster when the value is
increased, a machine may hunt, etc.
The orientation complete signal is output delaying the set time
0.5s 0 to 5s after in-position zone is entered. Also, the signal turns OFF
delaying the set time after in-position zone is out.
Orientation fault signal (ORM) is output when the encoder
remains stopped for the set time without orientation completion
in the state where orientation complete signal (ORA) is not
0.5s 0 to 5s
output even once. ORA signal is also output when the
orientation was started once but stopped without completing
the orientation before reaching to the set time.
Measure the time taken after passing the creep switchover
9999 0 to 60s position and output the orientation fault signal (ORM) if
orientation is not completed within the set time.
Turning OFF the start signal with orientation command (X22)
ON after stopping the motor by orientation control, the present
0 to 5s position is checked again after the set time elapses and the
9999
orientation complete signal (ORA) or orientation fault signal
(ORM) is output.
9999 Not checked.
Set the number of pulses of the encoder.
1024 0 to 4096
Set the number of pulses before multiplied by four.
0 Orientation is executed from the current rotation direction.
0 1 Orientation is executed from the forward rotation direction.
2 Orientation is executed from the reverse rotation direction.
60 0 to 1000
Response level during position control loop (servo rigidity) at
orientation stop can be adjusted.
0.333 0 to 20.0s
1 0 to 100.0 Lag/advance compensation gain can be adjusted.
Make adjustment when the motor rocks at orientation stop or
20 0 to 1000
the orientation time is long.
Set the number of encoder pulses at machine side. Set the
0 to 4096
9999
number of pulses before multiplied by four.
9999 Orientation control at machine side cannot be performed.
