Override Function; Acceleration And Decleration Time - Toshiba TOSVERT VF-S15 Instruction Manual

4.1.3. Override function

Speed type
Override functions (f660, f661) enable to add or multiply for fine adjustment of process value.
It is possible to set multiplication gain by analog input or parameter f729.
Refer to the inverter instruction manual for the detail of the setting.
* This function is valid also for process type PID, but it is rarely used.
4.1.4. Acceleration and deceleration time
Process type
Set the acceleration time (acc) and deceleration time (dec) to short for quick response.
But excessively small setting causes inverter trip.
Speed type
Speed PID control set the acceleration time and the deceleration time to the smallest automatically
regardless of parameter (acc,dec) setting
* Adjust each gain in case that the inverter trips. If you need to extend acceleration time and the
deceleration time, select the process type PID control.
