Operation mode
Speed control: Control the speed of motor accurately, related function codes in A5 group should be set.
Torque control: Control the torque of motor accurately, related function codes in A5 group should be set.
5.2.4 The channels to set the VFD frequency
SV100 supports 5 kinds of operating modes in speed control mode which can be sequenced according to the priority:
Jog>Close loop process operation>PLC operation>Multiple speed operation>simple operation. It is shown as follows:
Fig 5-4 Operating mode in speed control mode
The three operating modes provide three basic frequency sourse.Two of them can use the auxiliary frequency to
stacking and adjusting (except Jog mode), the descriptions of each mode are as follows:
1) JOG operation:
When the drive is in STOP state, and receives the JOG command (for example the M key on the panel is pressed), then
the drive jogs at the JOG frequency (refer to function code A2.04 and A2.05)
2) Close-loop process operation:
If the close-loop operating function is enabled (C1.00=1), the drive will select the close-loop operation mode, that is, it
will perform closed-loop regulation according to the given and feedback value (refere to function code C1 group). This
mode can be deactived by the multi-function terminals, and switch to the lower priority mode.
3) PLC operation
This function is customized, description is omitted.
