Chap. 9 FUNCTION CODES
When PID control is enabled:
The normal/inverse operation selection for the PID processor output (reference frequency) is
as follows.
PID control (Mode selection) (J01) IVS Final operation
OFF Normal
1: Enable (normal operation)
ON Inverse
OFF Inverse
2: Enable (inverse operation)
ON Normal
When the process control is performed by the PID processor integrated in the
inverter, the IVS terminal command is used to switch the PID processor outpu
(reference frequency) between normal and inverse, and has no effect on any
normal/inverse operation selection of the manual frequency setting.
Enable communications link via RS-485 -- LE
(Function code data = 24)
Turning this terminal command ON gives priorities to frequency commands or run
commands received via the RS-485 communications link (H30).
No LE assignment is functionally equivalent to the LE being ON. (Refer to the description of
H30.)
Reset PID integral and differential components -- PID-RST
(Function code data = 33)
Turning this terminal command ON resets the integral and differential components of the PID
processor.
Hold PID integral component -- PID-HLD
(Function code data = 34)
Turning this terminal command ON holds the integral components of the PID processor.
Run forward -- FWD
(Function code data = 98)
Turning this terminal command ON runs the motor in the forward direction; turning it OFF
decelerates it to stop.
This terminal command can be assigned only by E98 or E99.
Run reverse -- REV
(Function code data = 99)
Turning this terminal command ON runs the motor in the reverse direction; turning it OFF
decelerates it to stop.
This terminal command can be assigned only by E98 or E99.
E10 Acceleration Time 2 F07 (Acceleration Time 1)
E11 Deceleration Time 2 F08 (Deceleration Time 1)
Refer to the descriptions of function codes F07 and F08.
