Fixed Setting Mode Of High-Speed Operation Speed (F328=3, 4) - Toshiba TOSVERT VF-S15 Instruction Manual

3.3.2 Fixed setting mode of high-speed operation speed
(f328=3, 4)
《Adjustment method using the learning function for lift application》
When the light-load high-speed operation is carried out with normal operation of 60Hz, follow the
procedure below:
1) Set the automatic light-load high-speed operation frequency (f330).
2) Set the light-load high-speed learning function (f329) to 1 (Forward run learning).
3) Carry out the 60Hz-lifting (forward power running) operation while hanging the maximum load which
allows light-load high-speed operation and check that the operation switches to the light-load
high-speed operation (90Hz operation). (Forward run learning)
During the learning operation, tun blinks on the left side of the frequency display LED.
4) Set the light-load high-speed learning function (f329) to 2 (Reverse run learning).
5) Similarly, carry out the 60Hz-lowering (reverse regenerative braking) operation while hanging the
maximum load which allows light-load high-speed operation and check that the operation switches to
the light-load high-speed operation (90Hz operation).
During the learning operation, tun blinks on the left side of the frequency display LED.
6) The following parameters are automatically adjusted by carrying out operations in 3) and 5).

Heavy-load torque during constant power running
f338

7) Hang the minimum load which does not allow light-load high-speed operation and check that a
normal operation does not switch to either lifting (power running) or lowering (regenerative braking)
operations.
8) In case of a dynamic lift off at lifting (power running) operation, carry out the dynamic lift off after
high-speed operation and check that the inverter operates at the normal speed.
