5.5.2 Setting of Single-Phase AC Power Input/Three-Phase AC Power Input
Three-phase AC220V power supply input servo drive is of three-phase power supply input specifications, as
well as models that can be used under single-phase AC200V power supply input.
The servo drive models that can support single-phase AC220V power input are as follows.
HSD7-B(E)S-03A
, HSD7-B(E)S-06A
, HSD7-B(E)S-10A
,
HSD7-B(E)W-03A
, HSD7-B(E)W-06A
, HSD7-B(E)W-10A
,
When using the above servo-driven main loop power supply under single-phase AC220V power supply,
please change it to pn00b = n.

5.6 Function and setting of servo ON input (/S-ON) signal
The servo ON input (/S-ON) signal is a signal that enables the servo motor to enter an operational state.
The function and setting of the /S-ON signal will be described below.

/S-ON
Distribution required
ON (closed)
The servo motor is energized to enter a drivable

Servo motor is not energized and cannot be
driven.
The /S-ON signal can be set to Pn50a = n.
X
(servo ON input (/S-ON) signal distribution) and distributed
to terminals of other input signals.
Important
1. Please be sure to input speed command/position command/torque command after turning on /S-ON
signal to start or stop servo motor. If a command is input first, and then the motor is started or stopped by
turning on or off the /S-ON signal and AC power supply, internal components may be aged, resulting in
motor failure.
2. Please input /S-ON signal when the servo motor is stopped. The servo cannot be turned ON when
the motor rotates.
5.6.2 Set to Constant Servo ON (Motor Energized)
Pn50A = n.
X
(servo ON input (/S-ON) signal distribution) is set to 9 (when /S-ON signal is set to
constant servo on (motor on)), it can be set to constant servo on (motor on).

Set to Constant Servo ON (Motor Energized). (Fix the /S-ON
signal to always "active".)
Important
1. If the servo ON is set to always be valid, the motor will be powered on when the power supply of the
servo drive main loop is turned on. When the speed command/position command/torque command is input,
the servo motor or mechanical system may have unexpected actions, so please take safety measures.
2. Even if an inoperable state (non-energized state) is entered due to a resettable alarm, it will
automatically return to an operable state (energized state) as long as alarm reset is performed.
If the alarm reset is performed in the state of servo ON when it is set to normal, the servo motor or
mechanical system may have unexpected actions, so please pay attention.
5.7 Setting of Motor Rotation Direction
The rotation direction of the servo motor can be switched without changing the polarity of the speed
command/position command (command direction) (Pn 000 = n.
X
).
At this time, although the rotation direction of the motor will change, the polarity (phase relationship between
phase A and phase B) of output signals such as encoder frequency division pulse output will not change.
Please set according to the system.
