Handling the product without observing
the instructions that accompany a
“Warning” symbol may result in serious
injury or death.
Caution
Handling the product without observing
the instructions that accompany a
“Caution” symbol may result in injury or
property damage.
NOTE
The items under this heading contain
important handling instructions that the
user should observe to ensure safe use of
the product.
Warning
General
●
Do not use the product in explosive or corrosive
environments, in the presence of flammable
gases, locations subjected to splashing water,
or near combustibles. Doing so may result in
fire, electric shock or injury.
●
Installation, connection, operating/controlling,
inspecting and troubleshooting must be
performed by personnel with expert knowledge
of electrical and mechanical engineering.
Failure to do so may result in fire, electric shock
or injury.
●
Do not transport, install the product, perform
connections or inspections when the power is
on. Always turn the power off before carrying
out these operations. Failure to do so may
result in electric shock.
Connection
●
Keep the speed controller’s input-power voltage
within the specification to avoid fire and electric
shock.
●
Connect the cables securely according to the
wiring diagram in order to prevent fire and
electric shock.
●
Do not forcibly bend, pull or pinch the cable.
Doing so may result in fire and electric shock.
●
To prevent electric shock, be sure to install the
speed controller’s after making connections.
●
Be sure to insulate the connection terminal of
the external speed potentiometer. Failure to do
so may result in electric shock.
●
The speed controller has no built-in fuse for
overcurrent protection. Install a device for
overcurrent protection (e.g. fuse) before
connecting the unit to the power source. Failure
to do so may result in fire.
Operation
●
Turn off the speed controller power in the event
of a power failure, or the motor may suddenly
start when power is restored and may cause
injury or damage to equipment.
Maintenance and inspection
●
Do not touch the terminal block of the speed
controller’s motor and power immediately
after the power is turned off (for a period of 1
minute). This may cause electric shock.
Repair, disassembly and modification
●
Do not disassemble or modify the speed
controller. This may cause electric shock or
injury.
Safety precautions
The precautions described below are intended to prevent danger or injury to the user and other
personnel through safe, correct use of the product. Use the product only after carefully reading and fully
understanding these instructions.

■ Warning indication
Warnings are indicated on the cover of the speed
controller. Always observe such information
when handling the speed controller.
Caution
General
●
Do not use the speed controller beyond its
specification, or electric shock, injury or damage
to equipment may result.
Installation
●
Keep the area around the speed controller free
of combustible materials in order to prevent fire
or burning.
Operation
●
Use a speed controller and motor only in the
specified combination. An incorrect combination
may cause a fire.
●
Provide an emergency-stop device or
emergency-stop circuit external to the
equipment so that the entire equipment will
operate safely in the event of a system failure
or malfunction. Failure to do so may result in
injury.
●
Before supplying power to the speed controller,
set the Run/Stop input of the speed controller to
STOP (ON position).
Otherwise, the motor may start suddenly and
cause injury or damage to equipment.
●
Immediately when trouble has occurred, stop
running and turn off the speed controller power.
Failure to do so may result in fire, electric shock
or injury.
●
To prevent electric shock, use only an insulated
screwdriver to adjust the internal speed
potentiometer, acceleration time potentiometer
and deceleration time potentiometer.
Disposal
●
Dispose the product correctly in accordance
with laws and regulations, or instructions of
local governments.

How to install
■ Using screws
Secure the speed controller with two screws (M4: not supplied) through the two mounting holes
provided.
Tightening torque: 0.7 N·m (99 oz-in)
■ Mounting to DIN rail
Use a DIN rail 35 mm (1.38 in.) wide to mount the speed controller.
When removing from DIN rail, use force of about 10 to 20 N (2.2 to 4.5 lb.) to pull the DIN lever.
Installing and wiring in compliance with EMC directive
■ EMC directive
The compliance of the final machinery with the EMC directive must be verified through EMC measures
by the customer of the machinery.

■ Installing and wiring
◆ Connecting mains filter
Connect a mains filter specified in the table below, or the equivalent, to the AC input line, in order to
suppress the noise generated from the speed controller.
TDK Corporation ZAG2210-11S
EPCOS AG B84112-B-B110
Schaffner EMC FN2330Y-10-06, FN2310X-10-06
Tyco Electronics CORCOM 10ESK1
Install the mains filter as close to the speed controller as possible, and use cable clamps and other
means to secure the input and output cables firmly to the surface of the enclosure. Connect the ground
terminal of the mains filter to the grounding point, using as thick and short a wire as possible.
Do not place the AC input cable (AWG18: 0.75 mm2 or more) parallel with the mains-filter output cable
(AWG18: 0.75 mm2 or more). Parallel placement will reduce mains-filter effectiveness if the enclosure’s
internal noise is directly coupled to the power-supply cable by means of stray capacitance.
◆ Connecting surge arrester
Use a surge arrester or equivalent as below table.
OKAYA ELECTRIC INDUSTRIES CO.,LTD. RCM-601BQZ-4
PHOENIX CONTACT GmbH & Co. KG VAL-MS 230VF ST
NOTE
●
When measuring dielectric strength of the equipment, be sure to
remove the surge arrester, or the surge arrester may be damaged.
◆ Motor cable connection
When the motor cable is extended, use a cable of AWG18 (0.75 mm2) or more with a length of 10 m
(32.8 ft.) or less.
When extending the rate generator lead wires, use a shielded cable.
◆ Wiring the control cable
For the control cable for the speed controller, use a shielded cable as specified below, and keep it as
short as possible [2 m (6.6 ft.) or less ].
●
AWG28 (0.08 mm2) or more
●
The thickness of the insulator between the braided shield and lead-wire conductor shall be a minimum
of 0.4 mm (0.016 in.).
●
Recommended strip length for shielded cable
Wire
Insulation
Braided shield Sheath
4 mm (0.016 in.) min.

To ground a shielded cable, use a metal cable clamp or similar device that will maintain contact with the
entire circumference of the shielded cable. Attach a cable clamp as close to the end of the cable as
possible, and connect it to an appropriate grounding point as shown in the figure.
Shielded cable
Cable clamp
◆ Others
●
Connect the motor/speed controller and other peripheral control equipment directly to the grounding
point so as to prevent a potential difference from developing between grounds.
●
When relays or electromagnetic switches are used together with the system, use mains filters and CR
circuits to suppress surges generated by them.
●
Keep cables as short as possible without coiling and bundling extra lengths.
●
Place the power cables such as the motor and power-supply cables as far apart [100 to 200 mm
(4 to 8 in.)] as possible from the control cables. If they must cross, do so at a right angle. Place the
AC input cable and output cable of a mains filter separately from each other.
