F8 Group Auxiliary Function - HNC Electric HV610 Series User Manual

F7 - 02 small torque stop compensation
During torque control, the setting torque is too small to stop the traction load. At this time, F7 - 02 is added, and
the setting goes bigger, and the greater the torque during shutdown (note: not deceleration).
F7 - 04 torque control speed limit source
0: set speed limit by F7 - 05 and F7 - 06.
When the torque setting is greater than 0, the upper frequency limit is given by F7 - 05;
setting is less than 0, the upper frequency limit is set by F7 - 06.
1: set by frequency source F0 - 03 frequency source.
When the torque is set to be 0, the upper frequency limit is determined by the frequency selected by F0 - 03.
When the torque is set to be 0, the upper frequency limit is F0 - 03 negative number of selected frequency.
F7-05Torque control forward maximum frequency
F7-06Torque control reverse maximum frequency
During torque control, the acceleration / deceleration time of the upper frequency limit is set at F7 - 09
(acceleration) / F7 - 10 (deceleration).
Used to set the maximum forward or reverse operating frequency of the frequency inverter in torque control
mode.
When the frequency inverter torque is controlled, if the load torque is less than the motor output torque, the
motor speed will continuously increase. In order to prevent accidents such as speeding in mechanical systems, it is
necessary to limit the maximum rotational speed of the motor during torque control.
If it is necessary to dynamically and continuously change the maximum frequency of torque control, the upper
limit frequency can be controlled.
F7-07 Torque given rise time
F7-08 Given torque drop time
Under the torque control mode, the difference between the motor output torque and the load torque determines
the speed change rate of the motor and the load. Therefore, the speed of the motor may change rapidly, which will
cause problems such as noise or excessive mechanical stress. By setting the torque control acceleration and
deceleration time, the rotation speed of the motor can be changed smoothly.
However, when torque is required to respond quickly, torque control acceleration and deceleration time should
be set to 0.00s.
F7-09 Torque control frequency rise time
F7-10 Torque control frequency drop time
F8 - 00 cumulative power-on arrival time setting
When the accumulated power-on time (U0 - 71) reaches the power-on time set by F8 - 00, the frequency inverter
multifunction (No. 24) digital DO outputs the on signal.
