Chapter 1 Outline of HS-360 drivers
Each HS-360 driver is available exclusively for an RH/RHS/RFS/LA/LAH Series actuator, consisting of
a combined system of a small-sized precision control reduction gear Harmonic drive®and small DC
servomotor.
HS-360 drivers have many features to exhibit fully the characteristics of each actuator.
1-1 Main features
●Easy parameter setting
Parameters have been set to match the driver with the actuator you have ordered. Users do not
need to make any settings for the actuator, except in case of using particularly specific
parameters.
For this driver, the parameters to optimize the higher-level system and controllability can easily
be set or changed by viewing “Parameter mode” the seven-segment LED display.
●Substantial monitoring functions
The status of operation can be continuously displayed as either “Status display mode” or
“Numeric monitor mode”, and the settings of the desired parameters can be monitored.
Information of “Command”, “Feedback”, and “Error counter”, specifically important for the servo
system, can be monitored.
Up to eight previous events of “Alarm history” can be shown, and also the process diagnosing a
problem can be viewed.
●Easy test operation
In “JOG mode”, operating buttons on the panel enables “JOG” operation.
●Electronic gear suitable for mechanical system
The electronic gear "Command pulse input factor" function adjusts commands to the feed pitch
or angle of the driven mechanism.
●Three types of input signals for position commands
Three types of input signals for the position command are selectable: “Two-pulse train”,
“Single-pulse train”, and “Two-phase pulse train”.

Chapter 3 Control input/output
3-1 Command pulse input (CN1)
This inputs the pulse train input to FWD+, FWD-, REV+, and REV-.
This section shows a connection with a line driver command and that with an open collector command.
The standard input current shall be 20mA, while the maximum input current shall be 30mA.
◆ Connection with a line driver command
◆ Connection with an open collector command
●For +5V external power ●For +24V external power
If the +24V supply voltage is used with an open collector command, the
connection must be made in a different way.
For the supply voltage, “+5V” is the standard. For “+24V”, add a 1kΩresistor serially
to the connection. If the 1kΩresistor is omitted, the driver may break.
Caution
Encoder signal processing
The HS-360 driver executes the internal feedback process with a signal that is
obtained by multiplying the encoder feedback signal by 4.
By default, the amount of movement is obtained by multiplying the encoder resolution
by 4 relative to the command pulse input count.

3-2 Selecting the command pulse input configuration
Two ports of CN1-1&2 and CN1-3&4 are available for pulse input signals. Each of the signals input
through these two ports has one of three pulse input configurations.
◆ Setting a command configuration
[Parameter setup mode]→[31: selecting the pulse input configuration]
3-2-1 2-pulse train (FWD and REV pulse train)
As shown in the figure, “FWD commands” are input through the “FWD” port, while “REV commands”
through the “REV” port. While the input is in progress, keep the other port “off”. This is also called the
“FWD and REV pulse train method”, and is the default setting.
3-2-2 1-pulse train (polarity + pulse train)
One pair of terminals is assigned dedicatedly for command pulse train, and the other is assigned to a
sign for rotary direction. Position commands are input in the “FWD” port pair only and the “REV” port
pair accepts the sign of rotary direction, as shown in the figure below. [Off] or [Low level] state is for
the FWD command and [On] or [High] level is for the REV command.
3-2-3 2-pulse train (A-B phase pulses with 90-degree difference)
Both port pairs receive the command pulse trains that have a 90-electronic-degree difference relative
to each other as shown in the figure below. For the “FWD command”, the pulse train to the “FWD”
ports advances 90 degrees from the REV port train. For the “REV command”, the “REV” port train
advances from the FWD port train.
Actuator encoder monitor signals are output according to this method.

3-3 Control Input Signals (CN1, CN2)
This section shows connection examples and details of the functions with respect to the CN1 input
signals.
3-3-1 CN1 input signal connection and functions
The input signals are ENABLE, ALM-RST, and CLEAR.
The input circuit power supply is at DC 24V. (The input current is at approximately 10mA per circuit.)
Prepare it separately.
※ Values in ( ) are the values when 5V power supply is impressed.
External power supply of 5V is needed.
※ The voltage is set to 24V during preshipment inspection. Set all “1” to “4” on the DIP switch (DS1)
on the printed circuit board in the driver to “ON” when 5V power supply is impressed to the input circuit.
※ Select only 24V or 5V as voltage for external power supply.

CN1-5 Servo on: ENABLE
◆ Functions
(1) This signal turns on/off the driver circuit of the HS-360 driver.
When this input is on, the driver servo goes on, causing the driver to be ready. When it is off, the
servo goes off, causing the servo to be free, or the dynamic brake to be active.
(2) The dynamic brake on/off selection can be made by selecting [Parameter setup mode] →[46:
Dynamic brake on/off].
(3) The logic can be changed by selecting [Parameter setup mode] →[38: Input pin logic]. The default
is 0 (CLOSE), and the signal is meaningful.
(4) If [Parameter setup mode] is selected and 1 is selected in [41: CLEAR signal functions], the error
counter is also cleared and the error pulse count is set to 0.
◆ Connection
(1) For the input circuit power supply, prepare DC 24V separately.
(2) The input current is at approximately 10mA per circuit.
CN1-6 alarm reset: ALM-RST
◆ Functions
(1) When an alarm occurs
The alarm is cleared, and the driver is made ready. The edge is used for detection. If an
unclearable alarm occurs, turn off the power once. In this case, turn the power on again after
removing the cause of the alarm.
(2) The logic can be changed by selecting [Parameter setup mode] →[38: Input pin logic]. The default
is 0 (CLOSE falling edge), and the signal is meaningful.
(3) If [Parameter setup mode] is selected and 1 is selected in [41: CLEAR signal functions], the error
counter is also cleared and the error pulse count is set to 0.
 Connection
(1) For the input circuit power supply, prepare DC 24V separately.
(2) The input current is at approximately 10mA per circuit.
CN1-7 error counter clear: CLEAR
◆ Functions
(1) Clear the error counter, and set the error pulse count to 0.
(2) The logic can be changed by selecting [Parameter setup mode] →[38: Input pin logic]. The default
is 0 (CLOSE falling edge), and the signal is meaningful.
(3) If [Parameter mode] is selected and 0 is selected in [41: CLEAR signal functions], this input signal
will be enabled. If 1 is selected there, it will be disabled.
◆ Connection
(1) For the input circuit power supply, prepare DC 24V separately.
(2) The input current is at approximately 10mA per circuit.

CN1-8 input signal common: IN-COM
◆ Function
This is a common signal to “CN1-5, -6, and -7”, and supplies power form the outside for input
signals.
◆ Connection
The externally supplied voltage for input signals is “+24V”.
3-3-2 CN2 input signal connection and functions
FWD-LMT and REV-LMT are available for input signals.
No running torque is generated at the terminal through which this signal is being input.
For the input circuit power, prepare DC 24V separately (the current consumption is approximately
10mA per circuit).
CN2-31 FWD inhibit: FWD-LMT
CN2-33 REV inhibit: REV-LMT
◆ Functions
(1) FWD (or REV) inhibit: The actuator does not generate any forward (or reverse) torque while the
input signal is being generated. If both of the input signals are generated, the actuator
generates neither forward nor reverse torque. The inputs may be used to limit the motion range
between limit sensors.
(2) All pulses that are input to the detected portion during limit sensor detection are ignored.
(3) The logic can be changed by selecting [Parameter setup mode] →[38: Input pin logic]. The default
is 0. When the input signal causes the opti-isolator to be on, the limit function works.
◆ Connection
(1) For the input circuit power supply, prepare DC 24V separately.
(2) The input current is at approximately 10mA per circuit.
CN2-29 LMT signal power: LMT-Vcc
◆ Function
FWD-LMT and REV-LMT are power supply terminals.
◆ Connection
