 In V/F mode , If in no load condition current oscillation occurs causing motor vibration then adjust
parameter 01-12 to reduce this effect.
 Adjustment can be done in steps of 5 to 10%.

 In V/F mode, parameters 01-13,01-14 & 01-15 are used to prevent motor hunting by adjusting the
V/F output voltage level.
 01-13 Sets the hunting prevention response time constant (in msecs).
 01-14 Sets the Gain of the hunting prevention.
 01-15 Sets the hunting prevention voltage limit.
 Diagram below shows the Parameter relationships.

 Auto-torque Compensation function is effective in V/F mode. It can be used to correct insufficient
torque at low frequencies ( below 5 hz)
 Parameters 01-16 to 01-18 are effective after carrying out Auto tune function in SLV mode.
 Setting 01-17=0 Disables the auto torque compensation function.
