NOTE:
* Jog operation is effective in digital operator only. Jog mode can only be
entered while inverter is stopped.
* The jog frequency can be changed when inverter is in jog operation by pressing up or down keys
directly, without the need to set the function code to
Fn24
.
*The JOG function operates with momentary pushbutton closing only.
* In jog operation, absence of FWD or REV command will cause inverter to STOP. Inverter will
free run or brake to stop.
Fn25:
Master frequency reference.
Master frequency reference is used in digital operator control (
Fn11=0
)
NOTE:
* The master frequency can be changed when inverter is in run operation with up and down
arrow buttons without the need to set the function code to
Fn25
.
Example: When JOG key is pressed, inverter will run in jog mode no matter which frequency mode
is in use. If JOG key is pressed again, inverter will return to last frequency mode. Also, if inverter
is running in master frequency mode, frequency can be changed to multi-speed operation by turning
on speeds 2, 3, 4 or 5. Refer to
Fn17-25
.

Fn26:
BIAS of frequency reference.
Positive or negative frequency offset magnitude at initial starting point.
Fn27:
Positive / Negative BIAS
Fn27=0:

Fn27=1:
Negative Bias of frequency reference.
Fn28:
