Standard Type: CSK26
High-resolution Type: CSK26
SG Geared Type: CSK264
Power Supply
Keep the input power voltage 24 VDC10% or 36 VDC10%. Use a power
supply that can supply sufficient input current.
Notes
•
Keep the voltage Vo between 5 VDC and 24 VDC. When they are equal to 5
VDC, the external resistance R1is not necessary. When they are above 5 VDC,
connect R1to keep the current between 10 mA and 20 mA, and connect R2to
keep the current below 10 mA.
•
Use twisted-pair wire of AWG 24 (0.2 mm2) or thicker and 6.6 feet (2 m) or
less in length for the signal line.
•
Suitable wire size for the TB1, TB2 and TB3 connector is between AWG 20
and 26. Use AWG 20 (0.5 mm2) or thicker for motor lines ( when extended)
and power supply line.
•
Signal lines should be kept at least 3.94 inch (10 cm) away from power lines
(power supply lines and motor lines). Do not bind the signal line and power
line together.
•
Use spot grounding to ground of the driver and external controller.
•
If noise generated by the motor lead wire causes a problem, try shielding the
motor lead wires with conductive tape or wire mesh.
•
Incorrect connection of DC power input will lead to driver damage. Make sure
that the polarity is correct before turning power on.

Description of Input/Output Signals
Pulse (CW) Input and Rotation Direction (CCW) Input
Signal
1-Pulse Input Mode
Pulse Input Signal
"Pulse" signal is input to the PULSE/CWterminal. When the
photocoupler state changes from "ON" to "OFF", the motor
rotates one step. The direction of rotation is determined by
the rotation direction signal.
Rotation Direction Input Signal
The "Rotation Direction" signal is input to the
DIR./CCWterminal. A "photocoupler ON" signal input
commands a clockwise direction rotation. A "photocoupler
OFF" signal input commands a counterclockwise direction
rotation.
2-Pulse Input Mode
CW Pulse Input Signal
"Pulse" signal is input to the PULSE/CWterminal. When the
photocoupler state changes from "ON" to "OFF", the motor
rotates one step in a clockwise direction.
CCW Pulse Input Signal
"Pulse" signal is input to the DIR./CCWterminal. When the
photocoupler state changes from "ON" to "OFF", the motor
rotates one step in a counterclockwise direction.
All Windings Off Input Signal
When the "All Windings Off" (A.W. OFF) signal is in the
"photocoupler ON" state, the current to the motor is cut off
and motor torque is reduced to zero. The motor output shaft
can then be rotated freely by hand.This signal is used when
moving the motor by external force or to the manual home
position.
Excitation Timing Output Signal
The signal is output once each time the excitation
sequence returns to step “0” in synchronization with input
pulse. The excitation sequence is designed to complete
one cycle as the motor shaft rotates 7.2˚.
A signal is output every 4 pulses in full step mode and
every 8 pulses in half step mode. (When the “excitation
timing” signal is output, the transistor turns ON.)
