Adjustment of Operation
6.3 I/O Parameter 6.3.2 MEC Mode 1, MEC Mode 2 and MEC Mode 3
343
(8) Current limit value at stopping due to miss-pressing (Parameter No.9)
No. Name Symbol Unit Input Range Default factory setting
9
Current limit value at
stopping due to
miss-pressing
PSFC –
0: Current limiting
value at stop
1: Current limit
value during
pressing
0
This parameter defines the restricted current value at stopping due to miss-pressing.
This restricted current value locks the servo till the next moving command.
(9) Auto servo motor OFF delay time (Parameter No.10)
No. Name Symbol Unit Input Range Default factory setting
10
Auto servo motor OFF delay
time
ASO1 sec 0 to 9999 1
Set the duration before the servo turns OFF after positioning process is complete when the
power saving function is used.
[Refer to Chapter 5 Power-saving Function.]
(10) Stop mode selection (Parameter No.11)
No. Name Symbol Unit Input Range Default factory setting
11 Stop mode selection CTLF –
0: Full stop
1: Servo-motor stop
0 (Does not use)
This parameter defines the power-saving function.
For complete stop, the actuator stops with the servo being on.
For servo stop, it stops with the full servo control.
[Refer to Chapter 5 Power-saving Function.]
(11) Current-limiting value at standstill during positioning (Parameter No.12)
No. Name Symbol Unit Input Range Default factory setting
12
Current-limiting value at
standstill during positioning
SPOW % 1 to 70 35
When the value is increased, the stop holding torque is increased.
It is not necessary to change this setting in normal use. Movement due to external force can be
prevented by setting the value bigger in case a large force is applied during a stop. However,
there is a risk that motor or controller may burn if the setting is too high. Please contact IAI.
(12) Current-limiting value during home return (Parameter No.13)
No. Name Symbol Unit Input Range Default factory setting
13
Current-limiting value during
home return
ODPW % 1 to 100
In accordance with
actuator
The factory setting conforms to the standard specification of the actuator.
Increasing this setting will increase the home return torque.
It is not necessary to change this setting in normal use. Home-return operation may complete in
front of the proper point in some cases depending on how it is installed or load is attached when
the product is vertically mounted. It is necessary to increase the setting value in such cases.
Other causes can also be considered, so contact us in advance to making a change.
