Orientation position
loop gain

0.1 to 100
When servo torque function is selected using [
Pr.358
], output
frequency for generating servo torque increases to the creep
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.

Completion signal
output delay time
0.5s
0 to 5s
The orientation complete signal is output delaying the set time
after in-position zone is entered. Also, the signal turns OFF
delaying the set time after in-position zone is out.
{

364
Encoder stop check
time
0.5s
0 to 5s
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
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.
{
×
365 Orientation limit
9999
0 to 60s
Measure the time taken after passing the creep switchover
position and output the orientation fault signal (ORM) if
orientation is not completed within the set time.
{
×
366 Recheck time
9999
0 to 5s
Turning OFF the start signal with orientation command (X22)
ON after stopping the motor by orientation control, the present
position is checked again after the set time elapses and the
orientation complete signal (ORA) or orientation fault signal
(ORM) is output.
{
×
9999
Not checked.

Number of encoder
pulses
1024
0 to 4096
Set the number of pulses of the encoder.
Set the number of pulses before multiplied by four.

0
Orientation is executed from the current rotation direction.
×
{
1
Orientation is executed from the forward rotation direction.
2
Orientation is executed from the reverse rotation direction.
