To assign negative logic input to any input terminal, set
the function code to the value of 1000s shown in ( ) in
Section 5.1 " Function Code Tables." To keep explana-
tions as simple as possible, the examples shown below
are all written for the normal logic system.
• Select multi-step frequency (1 to 7 steps) – (SS1),
(SS2), and (SS4)
(Function code data = 0, 1, and 2)
Switching digital input signals (SS1), (SS2), and (SS4)
ON/OFF may switch the current set frequency to that
defined by function codes C05 through C11 (multi-step
frequencies). With this, the drive may drive the motor at
a maximum of 8 different speeds.
The table below lists the frequencies that can be
obtained by the combination of switching (SS1), (SS2),
and (SS4). In the column "Selected frequency," "Other
than multi-step frequency" represents the set frequen-
cies defined by frequency command 1 (F01), frequency
command 2 (C30), and others.

• Select acceleration/deceleration (2 steps) – (RT1)
(Function code data = 4)
Digital input signal (RT1) assigned to the specified
terminal ON/OFF may switch combinations between
acceleration/deceleration time 1 (defined by function
codes F07 and F08) and acceleration/deceleration time
2 (defined by E10 and E11).
Turning (RT1) ON, for example, enables the drive to drive
the motor using acceleration/deceleration time 2.
• Select 3-wire operation command – (HLD)
(Function code data = 6)
Digital input signal (HLD) may self-hold the forward
(FWD)/reverse (REV) run commands given at the external
signal input terminals to enable 3-wire drive operation.
Shorting the circuit between the (HLD)-assigned terminal
and terminal [CM] will self-hold the (FWD) or (REV) com-
mand. Opening the circuit will release the hold.

C10 (multi-step frequency 6)
C11 (multi-step frequency 7)
• Coast-to-stop command – (BX)
(Function code data = 7)
Shorting the circuit between the (BX)-assigned terminal
and terminal [CM] will immediately shut down the drive
output allowing the motor to coast to a stop without
issuing any alarm.
• Reset alarm – (RST)
(Function code data = 8)
When the protection facility has been activated (the
drive is in Alarm mode), shorting the circuit between the
(RST)-assigned terminal and terminal [CM] will reset the
alarm output on terminals [Y1] and [30A,B,C]. Opening
the circuit will release all the alarm indications to restart
operation. Allow 10 ms or more for the short-circuit time.
(RST) should be kept OFF for normal drive operation.
• Alarm from external equipment – (THR)
(Function code data = 9)
When the motor is running, opening the circuit between
the (THR)-assigned terminal and terminal [CH] will
immediately shut down the drive output and issue the
alarm "0H2." The motor will coast to a stop.
• Ready for jogging – (JOG)
(Function code data = 10)
Turning ON the (JOG) command makes the motor ready
for jogging. Use this command for fine adjustment of
workpiece positioning, for example.
When the motor is ready for jogging with (JOG) being
ON, pressing the key or turning the (FWD) or (REV)
command ON will start the motor to jog.
If the key is released, the motor will decelerate to a
stop.
Jogging operation follows the settings of:
– Jogging frequency set by function code C20
– Acceleration or deceleration time set by function
code H54
Simultaneous + keying may also make the motor
ready for jogging depending upon whether keypad
operation or terminal command operation is selected
and whether the (JOG) command is ON or OFF, as listed
below.
