EPFSIG
EPFSIG Selects a magnetic pole detection start signal.
0 : Uses SFR or SRV as a magnetic pole detection start signal.
1 : Uses EPFSTR as a magnetic pole detection start signal.
Set this parameter to select a desired start signal.
This parameter is valid in the automatic mode or direct current
activation mode.

Current ratio/motor stop confirmation time in magnetic pole detection operation
The upper three digits (ten thousands, thousands, and hundreds)
indicate a current ratio in magnetic pole detection, and the lower two
digits (tens and ones) indicate a motor stop confirmation time.
Current ratio in magnetic pole detection (upper three digits)
Unit of data : 1%
Valid data range : 0 to 99
Standard setting value : Depends on the motor model.
Set the magnitude of a current command value in magnetic pole
detection operation as a ratio to the maximum current value.
This parameter is valid in the automatic mode or direct current
activation mode.
Motor stop confirmation time (lower two digits)
Unit of data : 0.1sec
Valid data range : 0 to 99
Standard setting value : Depends on the motor model.
Set a period of time for confirming the stop of the motor in the direct
current activation mode.
This parameter is valid in the direct current activation mode.
Usually, this parameter need not be adjusted.
NOTE
If magnetic pole detection position precision is
insufficient for a cause such as friction, the motor
output torque may decrease. In such a case, this
parameter needs to be adjusted.
