VB5N series inverter
57
0: Disabled
1: Enabled
Inverter can saves the energy through detecting the load current; adjust output voltage when motor has no load or light load
running. This function is used to the situation of stable load and speed.
AVR is auto voltage regulation.When the input voltage of inverter fluctuates, AVR function can keep it stable.
When decelerating stop, if AVR is disabled, the decelerate time is short and the running current is large; if AVR is enabled,
the motor will stable decelerate, the running current is small and the decelerate time is longer.

2: Disabled in Dec process
slip frequency compensation
This function can make suitable regulation for inverter’s output frequency according to the load changing, and control the
speed at a certain value by dynamic compensating the slip frequency of asynchronism motor. If auto-torque boost function
is used together, better low speed torque characteristic can be obtained. As shown in Fig.4-13.

Accerlate time of jog operation
Dec time of jog operation
Jog operating frequency has the highest priority. No matter what status the inverter is, once there is a jog operating com-
mand input, the inverter will jog within Acc/Dec time of jog operation, as shown in Fig.4-14.
Acc time of jog operation means the time accelerate from 0 Hz to max frequency, Dec time of jog operation means the
time decelerate from max frequency to 0 Hz.
