4. Connection
(1) Basic Configuration
1) The general system configuration is as follows:
①CY-210E
The body of the constant-current resistance welding control. Connect AC
power to it.
②Thyristor contactor (Option)
Connects a welding power source to this device.
③Toroidal coil (Option)
Installed to the arm of the welding head. This is unnecessary in the primary
constant current control.
④Connecting cable
Connects the controller to the welding-robot controller. Please provide
separately
⑤Welding robot
An articulated robot. Prepare it separately.
2) Precautions for installation
①Confirm that the control is installed (fixed) securely at the specified
locations.
②Confirm the welding power source. The voltages for this device are
indicated below the terminal block.
③Ground the control securely.

(2) Connection of Power Source
1) Connect the power source to the power-supply terminal block mounted on the rear
panel.
①Connect the thyristor contactor to the power-supply terminal block on the
rear panel of CY-210E, as shown below.
②Securely connect each wire. Take care not to confuse the Nos. of the wires.
③Connect 02/(02) to the terminal for the voltage being used.
The connection of 01, (02) or 02 is important for the operation of the thyristor.
If it is connected improperly [if 01 and (02) or 02 are connected inversely], the
thyristor cannot be conductive. It must therefore be connected properly and
securely.
When no power-supply error is detected and the current does not flow even
though the power is supplied correctly and CY-210E starts normally, make
sure that 01 and (02) or 02 are not connected inversely.
④Be sure to ground the control.
Ground the E terminal (grounding) of CY-210E in common with the
grounding of the thyristor contactor.
Note: The thyristor contactor, welding transformer, welding head, and
connecting cable are optional.

(3) Installation Method for the Current-Detecting Coil
1) Installation Method for a Toroidal Coil
①Install the toroidal coil to the secondary side of the welding transformer.
If only one welding head is used, install the toroidal coil as shown below:
Primary side
Toroidal coil
Welding head
Welding transformer
Fig.1 Connector methods for toroidal coil (1)
If two or more welding heads are used, install the toroidal coil as shown
below:
•When only one welding head welds at a time

Fig.3 Connector method for toroidal coil (3)
②Set dip switch DSW1-(2) to the OFF position (see page 4-7).
③Precautions on installation of the toroidal coil
If the toroidal coil is broken in the constant-current control mode, no
power-supply error is detected and the operation stops. A proper installation
position must therefore be selected for the toroidal coil so that it will not be
broken by the temperature rise of the conductor, mechanism motion,
contact with a workpiece, or the like. In addition, secure the toroidal coil to
the conductor using a band, etc. If the toroidal coil is wound onto the
conductor as shown in Fig. 4-A, an error occurs. Accordingly, wind it as
shown in Fig. 4-B.
Note: No power-supply error is detected in the source-voltage fluctuation
compensation control mode.
Note: The thyristor contactor, welding transformer, welding head, and
connecting cable are optional.

④Checking for breakage and short-circuiting of the toroidal coil
Breakage of and shorts in the toroidal coil can be checked using a tester, as
the toroidal coil has the internal resistance shown in Fig. 5.
(Keep in mind that the internal resistance changes depending on the type of
toroidal coil.)
Toroidal coil Internal resistance
MB-400L 35–65Ω
MB-45F 130–165Ω
Fig. 5 Internal resistance of toroidal coil
The sensitivity of each toroidal coil is adjusted so that it will detect the current
accurately. If the cable is cut halfway and extended, or if the connector is
disassembled, the current cannot be kept constant. (When using the
toroidal-coil remote, use a special extension cable.)
2) Installation Method for a CT Coil
①Install a CT coil to the primary side of the welding transformer.
CT coil
Welding power supply
Welding transformer
Welding head
Thyristor contactor
②Set dip switch DSW1-(2) to the ON position (see page 4-7).
③Precautions on use of a CT coil
Use a CT coil with a rated primary current of 600 A and a secondary current
of 5 A. Connect a resistor of 0.2 Ω10 W to its secondary side, then connect
both ends to the CY-210E using special connector 14-2A (manufactured
by KOMINE MUSEN ELECTRIC CORPORATION).
Note: The thyristor contactor, welding transformer, welding head, and
connecting cable are optional.
Note: The model number of connector is subject to change without notice.
Depending on the part to be changed, the mounting screw shape
may change and a necessary tool may be different. For the latest
parts information, contact a nearest sales office.

3) Explanation of functions of dip switches
①DSW1-(1) •Selects the constant-current control or source-voltage
fluctuation compensation control.
OFF: Constant-current control
ON: Source-voltage fluctuation compensation control
②DWS1-(2) •In constant-current control mode (DSW1-(1): OFF)
OFF: Constant-current control method with
secondary-current feedback
ON: Constant-current control method with
primary-current feedback
•In source-voltage fluctuation compensation control mode
(DSW1-(1): ON)
OFF: Secondary-current feedback detection mode. By
connecting a toroidal coil, the measured value of the
welding current can be indicated and full-wave
errors can be detected.
ON: Primary-current feedback detection mode. By
connecting a CT coil, the welding current can be
measured and full-wave errors can be detected.
When using the primary-current feedback detection
mode, set the turn ratio of the transformer so that the
current can be measured properly (see page 6-11).
③DSW1-(3) •Select the signal to be output to Pin 23 in the terminal block
on the rear panel.
OFF: Output of power-on timing signal
ON: Output of flicker
If this dip switch is set to OFF, the power-on timing signal is
output after Weld I starts and continues to be output until
Weld III finishes, regardless of the setting of Weld ON/OFF.
If this dip switch is set to ON, the flicker signal is output
only during power-on in Weld I, Weld II, and Weld III. The
power-on timing signal and the flicker signal are output
from the power-on signal [WELD ON].
④DSW1-(4) •Sets the start-signal parity-check function when the
controller is started up in 15-schedule mode.
OFF: Parity check will not be executed.
ON: Parity check will be executed.
If this dip switch is set to OFF, the parity check will not be
executed. If it is set to ON, the parity check will be
executed, and a start-input error signal (Error code [02])
will be output if a parity error is detected. Odd parity is
checked. For details, see "(5) Input Method for Start
Signals, 2)" on page 4-11.
⑤DSW1-(5) •Selects the self-holding timing for the start signal.
OFF: Self-holding of start signal at weld start
ON: Self-holding of start signal at squeeze
If this dip switch is set to OFF, the start signal is held when
the welding (Weld I) starts. If it is set to ON, the start signal
is held when the initial weld force (Squeeze) starts.

CY-210E
4.Connection
4-8
⑥DSW1-(6) •Makes settings so that the power will or will not be supplied again
when the lower current limit is detected or no current flows.
OFF: Re-power-on---OFF
ON: Re-power-on---ON
If this dip switch is set to OFF, power is not supplied again.
If it is set to ON, current increased by 5% is supplied (see
4) on page 5-7).
Note: This does not apply in the source-voltage fluctuation
compensation control mode.
⑦DSW1-(7) •Selects the length of time for which the holding finish signal is
output.
OFF: Output of holding-finish-signal level
ON: Output of holding-finish-signal pulse
If this dip switch is set to OFF, the holding finish signal is
output for approximately 0.2 seconds or while the start
signal is input. If this dip switch is set to ON, the holding
finish signal [HOLD END] is output for 0.2 seconds.
⑧DSW1-(8) •Selects the action to be taken in the event of a current-monitor
error.
OFF: When there is a problem with the current monitor, a
holding finish signal is output and welding can be
started again.
ON: When there is a problem with the current monitor, a
holding finish signal is not output and welding cannot
