ELECTRIC INVERTER,S ENERGY SAVING FREQUENCY AND ZERO SERVO GAIN.

ENERGY SAVING FREQUENCY.

this is the frequency lower limit within the effective range of energy saving control . it is set in unit of Hz . please set the frequency lower limit within the effective range of energy saving control. energy saving command . it starts only from the frequency which is above the lowest energy saving frequency . it is only effective in the situation with uniform speed.
setting range is 0.0~400.0.
factory setting is  0.0.
v/f is a.
v/f with pg is a


ZERO SERVO GAIN.









it is used to adjust the strength of zero servo lock . the zero servo function is enabled when one of the multi function inputs is set to zero servo command . if the zero servo command is on when the factory (speed) reference falls below the zero speed level (b 2 -01) , a position control loop is formed and the motor is stopped. if zero servo gain is set be a comparatively bigger value, the lock strength will be bigger too . if it is too big vibration will occur .
