KEYPAD (HMI) OPERATION
5.2.1 Keypad
Operation
62
All functions relating to the CFW-08 operation (Start/Stop, Direction of
Rotation, JOG, Increment/Decrement of the Speed (Frequency) Reference,
and selection of LOCAL/REMOTE mode) can be performed through the
HMI selection. For factory default programming of the inverter, all keypad
keys are enabled when the LOCAL Mode has been selected. These same
functions can be performed through digital and analog inputs. Thus you
must program the parameters related to these corresponding inputs.
NOTE!
The control keys ,
P229=0 for LOCAL Mode operation
P230=0 for REMOTE Mode operation
The key depends of the parameters above and if:
P231=2
Keypad keys operation description:
When enabled (P220 = 2 or 3), selects the control input and the speed
reference (speed) source, toggling between LOCAL and REMOTE Mode.
When pressed, starts the motor according to acceleration ramp up to the
speed (frequency) reference. The function is similar to that
performed through digital input START/STOP, when it is closed (enabled)
and maintained enabled.
Stop disables the inverter via deceleration Ramp.The Function is similar
to that performed through digital input START/STOP, when it is open
(disabled) and maintained disabled.
When the JOG key is pressed, it accelerates the motor according to the
acceleration ramp up to the JOG speed programmed in P122.
This key is only enabled when the inverter digital inputs, programmed to
general enable (if any) are closed.
When enabled (refer to the note above), reverses the motor direction of
rotation.
Motor speed (frequency) setting: these keys are enabled for speed setting
only when:
the speed reference source is the keypad (P221 = 0 for LOCAL Mode
and/or P222 = 0 for REMOTE Mode);
the following parameter content is displayed: P002, P005 or P121.
Parameter P121 stores the speed reference set by these keys.
When pressed, it increases the speed (frequency) reference.
When pressed, it decreases the speed (frequency) reference.
and are only enabled if:
