SP045 CSNT Dual cushion timer
Set the cycle to add the increment values in the dual
cushion process.
When this setting value is increased, the dual cushion will
increase, and the changes in the speed during
acceleration/deceleration will become gradual.
0 to 1000 (ms) 0
SP046 CSN2*
Speed command dual
cushion
For an acceleration/deceleration time constant defined in
SP019 (CSN1) , this parameter is used to provide smooth
movement only at the start of acceleration/deceleration.
As the value of this parameter is smaller, it moves
smoother but the acceleration/deceleration time becomes
longer.
To make this parameter invalid, set "0".
0 to 1000 0
SP047 SDTR*
Speed detection reset
value
Set the reset hysteresis width for a speed detection set
value defined in SP020 (SDTS).

SP048 SUT* Speed reach range
Set the speed deviation rate with respect to the
commanded speed for output of the speed reach signal.
0 to 100 (%) 15
SP049 TLM2 Torque limit 2 Set the torque limit rate for the torque limit signal 010. 0 to 120 (%) 20
SP050 TLM3 Torque limit 3 Set the torque limit rate for the torque limit signal 011. 0 to 120 (%) 30
SP051 TLM4 Torque limit 4 Set the torque limit rate for the torque limit signal 100. 0 to 120 (%) 40
SP052 TLM5 Torque limit 5 Set the torque limit rate for the torque limit signal 101. 0 to 120 (%) 50
SP053 TLM6 Torque limit 6 Set the torque limit rate for the torque limit signal 110. 0 to 120 (%) 60
SP054 TLM7 Torque limit 7 Set the torque limit rate for the torque limit signal 111. 0 to 120 (%) 70
SP055 SETM*
Excessive speed
deviation timer
Set the timer value until the excessive speed deviation
alarm is output.
The value of this parameter should be longer than the
acceleration/deceleration time.
0 to 160 (s) 12
SP056 PYVR
Variable excitation
(min value)
Set the minimum value of the variable excitation rate.
Select a smaller value when gear noise is too high.
0 to 100 (%) 50
SP057 STOD*
Constant → transition
judgment value
Set the value for judging when changing the speed
command from a constant to acceleration/deceleration.
When "0" is set, judge the speed with 12 r/min.
0 to 50 (r/min) 0
SP058 SDT2*
Speed detection setting
value 2
Set the motor speed for carry out speed detection 2
output.
0 to 32767

SP059 MKT*
Winding changeover
base shut-off timer
Set the base shut-off time for contactor switching at coil
changeover.
Note that the contactor may be damaged with burning if
the value of this parameter is too small.
50 to 10000

SP060 MKT2*
Current limit timer after
coil changeover
Set the current limit time to be taken after completion of
contactor switching at coil changeover.

SP061 MKIL*
Current limit value after
coil changeover
Set the current limit value during a period defined in
SP060 (MKT2) after completion of contactor switching at
coil changeover.
0 to 120 (%) 75
SP062 Not used. Set to "0". 0 0
SP063 OLT*
Overload alarm detection
time
Set the time constant for detection of the motor overload
alarm.
(For machine tool builder adjustment)
0 to 1000 (s) 60
SP064 OLL*
Overload alarm detection
level
Set the detection level of the motor overload alarm.

SP065 VCGN1*
Target value of variable
speed loop proportional
gain
Set the magnification of speed loop proportional gain with
respect to SP022 (VGNP1) at the maximum motor speed
defined in SP017 (TSP).
0 to 100 (%) 100
Parameters with an asterisk * in the abbreviation, such as OSP*, are validated with the NC power turned ON again.
