Chap. 4 RUNNING THE MOTOR
Run commands from the keypad in the local mode
The table below shows the input procedures of run commands from the keypad in the local mode.
When F02 data (run command) is: Input procedures of run commands from keypad
0: Enable / keys on keypad
(Motor rotational direction from digital
terminals [FWD]/[REV])
Pressing the
key runs the motor in the direction specified by command
FWD or REV assigned to terminal [FWD] or [REV], respectively.
Pressing the
key stops the motor.
1: Enable terminal command FWD/REV
2: Enable /
keys on keypad (Forward)
Pressing the
key runs the motor in the forward direction only. Pressing
the key stops the motor.
No specification of the motor rotational direction is required.
3: Enable /
keys on keypad (Reverse)
Pressing the
key runs the motor in the reverse direction only. Pressing
the key stops the motor.
No specification of the motor rotational direction is required.
Switching between remote and local modes
The remote and local modes can be switched by a digital input signal provided from the outside of the inverter.
To enable the switching, you need to assign LOC as a digital input signal to any of terminals [X1] to [X7] by setting "35" to any
of E01 to E07, E98 and E99.
Switching from remote to local mode automatically inherits the frequency settings used in remote mode. If the motor is running
at the time of the switching from remote to local, the run command will be automatically turned ON so that all the necessary
data settings will be carried over. If, however, there is a discrepancy between the settings used in remote mode and ones made
on the keypad (e.g., switching from the reverse rotation in remote mode to the forward rotation only in local mode), the inverter
automatically stops.
The transition paths between remote and local modes depend on the current mode and the value (ON/OFF) of LOC, as shown in
the status transition diagram given below. Also, refer to above table for details.
Transition between Remote and Local Modes by LOC
4.2.3 External run/frequency command
By factory default, run and frequency commands are sourced from the keypad. This section provides other external command
source samples--an external frequency command potentiometer (variable resistor) as a frequency command source and external
run switches as run forward/reverse command sources.
Set up those external sources using the following procedure.
(1) Configure the function codes as listed below.
Function code Name Data Factory default
f
01
Frequency command 1 1: Analog voltage input to terminal [12]
0
f
02
Operation method 1: External digital input signal
2
e
98
Terminal [FWD] function 98: Run forward command FWD
98
e
99
Terminal [REV] function 99: Run reverse command REV
99
If terminal [FWD] and [REV] are ON, the F02 data cannot be changed. First turn those terminals OFF and then
change the F02 data.
(2) Wire the external frequency command potentiometer to terminals across [13], [12], and [11].
(3) Connect the run forward switch between terminals [FWD] and [CM] and the run reverse switch between [REV] and [CM].
(4) To start running the inverter, rotate the potentiometer to give a voltage to terminal [12] and then turn the run forward or
reverse switch ON (short-circuit).
For precautions in wiring, refer to Chapter 2 "MOUNTING AND WIRING THE INVERTER."
