PRM No. Parameter name
UP-07 In-position width
This parameter specifies, by the number of motor sensor pulses, the position deviation for outputting
the positioning completed signal (INP).

PRM No. Parameter name
UP-11 Current limit value
This parameter specifies the maximum current provided to the motor, with the motor's momentary
maximum current as 100%.
Use this parameter to limit the torque added to the mechanical system.
PRM No. Parameter name
UP-14 S-curve acceleration/de-
celeration time
This parameter specifies the S-curve (filter characteristic) for the acceleration/deceleration time
(PP-20 to PP-23).
Use this parameter to suppress the impact to the mechanical system during acceleration and decel-
eration.
If the acceleration/deceleration time is 0, this will become the time until 90% of the target speed is
obtained.
When this parameter is set to "0.00," the S-shaped acceleration/deceleration will be invalidated and a
trapezoidal curve will be employed according to the acceleration/deceleration time (PP-20 to PP-23).
PRM No. Parameter name
UP-16 Brake mode
This parameter specifies the brake output (BO) function and the method for stopping the motor when
the RUN command is OFF.
Set value
0 Brake output: dynamic brake; stop method: free-running stop
1 Brake output: on-hold brake; stop method: stop in deceleration time during execution
2 Brake output: on-hold brake; stop method: stop after rotation according to error counter's
accumulated number of pulses
3 Brake output: on-hold brake; stop method: free-running stop
Note After setting this parameter, turn OFF the power and check to be sure that the displays have
turned OFF before turning the power back ON again. (The new setting will go into effect when the
power is turned back ON.)
