LED Status Lights

There are two LED lights. The GREEN one is the power indicator which should be always on in normal
circumstance.The RED one is a alarm status indication light, which will be OFF while working normally but
ON and flash some timesin a 3-second period in the case of enabled alarm protections.

Switches

The CL42T(V4.1) has one rotating switch, one 8-bit DIP switch and one 1-bit selector switch.

4. Power Supply Selection

The CL42T(V4.1) can power medium and large size stepping motors (frame size from NEMA 8 to 17). To get
good driving performances, it is important to select supply voltage and output current properly. Generally
speaking, supply voltage determines the high speed performance of the motor, while output current determines
the output torque of the driven motor (particularly at lower speed). Higher supply voltage will allow higher motor
speed to be achieved, atthe price of more noise and heating. If the motion speed requirement is low, it's better
to use lower supply voltage todecrease noise, heating and improve reliability.

Power Supply Sharing

Multiple CL42T(V4.1) drives can share one power supply to reduce cost, if that power supply has enough
power capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply
separately. Toavoid cross interference, DO NOT daisy-chain connect the power supply input pins of the Drivers.
Instead connect them to power supply separately.

Selecting Supply Voltage

The CL42T(V4.1) is designed to operate within 18 - 50VDC voltage input. When selecting a power supply,
besidesvoltage from the power supply power line voltage fluctuation and back EMF voltage generated during
motor deceleration needs also to be taken into account. Please make sure leaving enough room for power line
voltagefluctuation and back-EMF voltage charge back, it's recommended 24 - 48VDC.
