F25 Stop Speed
H66 (Stop Speed, Detection method)
H67 (Stop Speed, Holding time)
F25, H66, and H67 specify the stop speed, its detection method, and its holding time, respectively, to
reduce an impact to the load at the end of travel.
■
Stop speed (F25)
F25 has diferent behaviors depending on the control mode. In case of Torque vector control it is stop
speed, in other words, at deceleration to stop motor will keep running at F25 speed as long as run
command is ON. In case of Vector control (with PG) it is just a speed level, in other words, motor
will decelerate to 0.00 rpm at stop even F25 is different than 0.00 rpm.
- Data setting range: 0.00 to 150.0 (r/min)

Data setting range changes depending on the number of poles of motor etc. For details, refer to
section 2.2.
■
Detection method (H66)
H66 selects whether to use the detected speed or reference speed (final) for detecting the stop speed.
Data for H66 Function
0 Use detected speed*
1 Use reference speed (final)
* In case of Torque vector control, inverter will use reference speed (final) as well.
■
Holding time (H67)
H67 specifies the time that, inverter will keep main output circuit ON after stop speed (F25) level is
reached even run command is removed before.
If H67 is 0.00 s, and run command is removed before stop speed (F25) level is reached, inverter will
switch OFF main output circuit as soon as F25 level is reached.
- Data setting range: 0.00 to 10.00 (s)
