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

ENERGY SAVING GAIN.


set the inverters output voltage when the energy saving command is given.

note:when the energy  saving command is given , please set the inverters output voltage in unit of% with the set voltage of v/f curve taken as 100%. to set the voltage change according to voltage recovery time under the  command of on off..

ENERGY SAVING FREQUENCY.

this is the frequency lower limit with in th effective range of energy saving control . it is set in unit of Hz. please set the frequency lower limit with in 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.



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 frequency ( 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 .
