5-20
Edit permission command (data change
permission)(WE-KP) (data protection)
Value 19: This function allows the data to be changed
only when input is received from an external signal,
thereby preventing function code data changes.
19 Selected Function
off Prohibit data changes
on Allow data changes
Note: If a terminal is assigned the value 19, the data
cannot be changed. To change data, turn the terminal on
and change its setting to another number.
PID control cancellation (Hz/PID)
Value 20: The PID control can be disabled by an external
digital input signal.
Input Signal Selected Function
20 [Related Functions: H20-H25]
off Enable PID control
on Disable PID control
(When the PID control is disabled, the frequency is set
from keypad panel)
Normal operation/inverse
Value 21: Analog input (Terminals 12 and C1) can be
switched between normal and inverse operations using an
external digital input signal.
Input Signal Selected Function
21 [Related Function: F01]
off
Normal operation if normal operation is
set and vice versa
on
Inverse operation if normal operation is
set and vice versa
Interlock (52-2)
Value 22: When a contactor is installed on the output side
of the drive, the contactor opens at the time of a momen-
tary power failure. This prevents the reduction of the DC
circuit voltage and may prevent the detection of a power
failure and a correct restart operation after power is
recovered. The restart operation, in the event of a
momentary power failure, can be performed effectively
with power failure information provided by an external
digital input signal.
Torque limit 2/torque limit 1
Value 14: Frequency setting 2/frequency setting 1. This
function switches the torque limit value set with function
codes F40, F41, E16, and E17, using an external digital
input signal.

Switching operation from line drive
(60Hz)(SW60)/(50Hz)(SW50)
Value 15, 16: Motor operation can be switched from 60
Hz/50 Hz commercial power to drive operation without
stopping the motor by switching the external digital input
signal.
Input Signal Function
16
off > on Drive operation to line operation (60 Hz)/(50 Hz)
on > off Line operation to drive operation (60 Hz)/(50 Hz)
Following a momentary power failure, if the digital input
signal goes off, 50 or 60 Hz (according to the input
signal) is output after the restart waiting time (function
code H13). The motor is then directed to drive opera-
tion.
UP command (UP)/DOWN command (DOWN)
Value 17, 18: When an operation command is input (on),
the output frequency can be increased or decreased
using an external digital input signal.
The change ranges from 0 to maximum frequency.
Operation in the opposite direction, of the operation
command is not allowed.
Selected Function
(when operation command is on)
18 17
off off Holds the output frequency
off on
on off
on on Holds the output frequency
Increases the output frequency
according to the acceleration time
Decreases the output frequency
according to the deceleration time
Combination
of Input Signals
There are the two types of UP/DOWN operations as
shown below. Select the desired type by setting the
frequency (F01 or C30).
