How To Adjust Parameters; Automatic Setting Mode Of High-Speed Operation Speed (F328=1, 2) - Toshiba TOSVERT VF-S15 Instruction Manual

3.3 How to adjust parameters

If the light-load high-speed operation is used, be sure to set the motor-related parameters (Motor
constants).
Refer to Section 6.25 of VF-S15 instruction manual (E6581611) to set motor-related parameters.
In addition, for the high-speed operation fixed setting mode (f328=3, 4), learning function simplifies
the adjustment of the light-load high-speed operation.
3.3.1 Automatic setting mode of high-speed operation speed
(f328=1, 2)
《Adjustment method 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 parameter below at an arbitrary position of the status monitor display selection (f711 to
f718).
Torque monitor
2) Set f328=0 to avoid switching to the light-load high-speed operation.
3) Check the torque monitor value of the following conditions and set the value.
Use the maximum load which allows light-load high-speed operation.
Lifting (Up): Power running operation
τ1: steady torque at base frequency (vl)
τ2: maximum torque during acceleration up to base frequency (vl) operation
τ3: steady torque at light-load high-speed frequency operation (upper limit frequency (ul))
τ4: maximum torque during acceleration up to light-load high-speed frequency operation (upper limit
frequency (ul))
Lowering (down): Regenerative braking operation
τ5: steady torque at base frequency (vl)
τ6: minimum torque during acceleration up to base frequency (vl) operation
τ7: steady torque at light-load high-speed frequency operation (upper limit frequency (ul))
τ8: minimum torque during acceleration up to light-load high-speed frequency operation (upper limit
frequency (ul))
*τ6 and τ8 are for reference.
