PS01 **LIT1 Special function selection 1
The magnetic pole detection setting and the valid/invalid setting of the direct drive
motor thermistor can be selected. (Refer to section 14.4.2.)
Direct drive motor magnetic pole detection setting is unnecessary for an incremental
system.
Direct drive motor magnetic pole detection setting
0: Magnetic pole detection invalid
1: Magnetic pole always valid
0 0
Direct drive motor thermistor valid/invalid setting
0: Thermistor error detection valid
1: Thermistor error detection invalid
Each 0301h Refer to
Name

function
column.
POINT
To protect the direct drive motor from overheating, usually
fabricate a cable that includes a thermistor wire. Set the
thermistor error detection to be valid with this parameter.
PS02 This parameter is not used. Do not change this value by any means. 1000
PS03 1000
PS04 *LIT2 Special function selection 2
Servo control error detection function and servo control error reset can be selected.
Servo control error detection function selection
(Refer to section 14.4.4)
0: Invalid
1: Position deviation error detection valid
2: Speed deviation error detection valid
3: Position/speed detection deviation error
detection valid
4: Torque deviation error detection valid
5: Position/torque deviation error detection valid
6: Speed/torque deviation error detection valid
7: Position/speed/torque deviation error detection
valid
Servo control error detection reset selection
Set the controller reset condition of the servo
control error detection (42. ).
0: Reset impossible (Reset by switching off is
possible.)
1: Reset possible
0 0
Each 0003h Refer to
Name

function
column.
PS05 LB1 Servo control position deviation error detection level
This is used to set the position deviation error detection level of the servo control
error detection. When the deviation between a model feedback position and actual
feedback position is larger than the setting value, Servo control error (42.1) will occur.
(Refer to section 14.4.4.)
Setting "0" will be regarded as 0.09rev by the servo amplifier.
Each 0 0.01rev 0 to
1000
PS06 LB2 Servo control speed deviation error detection level
This is used to set the speed deviation error detection level of the servo control error
detection. When the deviation between a model feedback speed and actual feedback
speed is larger than the setting value, Servo control error (42.2) will occur. (Refer to
section 14.4.4.)
Setting "0" will be regarded as 100r/min by the servo amplifier.
Each 0 r/min 0 to
2000
