CHINT NVF2G-S Series - Jogging Operation

When a power failure occurs in the system, the frequency converter keeps the motor in power generation
state to maintain the bus voltage at FE.16, preventing the frequency converter from shutting down due to short
-term input voltage cutoff resulting in undervoltage fault.

Parameter Description
● In deceleration mode: when the power grid is restored, the output frequency of the inverter will return
to the target frequency according to the acceleration time;
● In deceleration stop mode: When the power grid is restored, the inverter will continue to decelerate to
0Hz to stop, and the inverter will not start until the inverter sends a start command again.
8.13 Jogging operation
In some applications, it is necessary for the inverter to run at a low speed for a short time, which is
convenient for testing the condition of the equipment. At this time, jogging operation is used. During jogging
operation, the starting mode is fixed as direct start mode F1.00=0, and the stop mode is fixed as deceleration
stop mode F1.05=0.
The "MF" key on the operation panel can be used to control the jogging operation (F7.02=0), and the digital
input terminal (X) can also be used to realize related functions.
