Toshiba Tosvert VF-S15 Instruction Manual page 192

1) To suspend acceleration or deceleration automatically
Set the frequency with f350 or f352 and the time with f351 or f353, and then set f349 to 1.
When reached the set frequency, the motor stops accelerating or decelerating to run at a constant speed.
Output frequency [Hz]
2) To suspend acceleration or deceleration by means of a signal from an external control device
Set 60 for an input terminal. As long as ON signals are inputted, the motor continues to rotate at a constant
speed.
Output frequency [Hz]

Function No. 61 is the inversion signal.
Note: If the operation signal is ON after Acceleration/ deceleration suspend signal is ON, the inverter will operate
at frequency set with f240.
 If the stall control function is activated during constant-speed rotation
The frequency changes momentarily as a result of stall control, but the time for which the frequency changes is
included in the suspend time.
