3.4 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 times in a 3-second period in the case of enabled alarm protections.

4. Power Supply Selection

The CL86T (V4.0) can power medium and large size stepping motors (frame size from NEMA 17 to 24). 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, at the price of more noise and heating. If the motion speed
requirement is low, it's better to use lower supply voltage to decrease noise, heating and improve reliability.

4.1 Power Supply Sharing

Multiple CL86T (V4.0) 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. To avoid cross interference, DO NOT daisy-chain connect the power supply input pins of the
drivers. Instead connect them to power supply separately.

4.2 Selecting Supply Voltage

The CL86T (V4.0) is designed to operate within 24 - 110VDC or 18 - 80VAC voltage input. When selecting a
power supply, besides voltage 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 voltage fluctuation and back-EMF voltage charge back.
Higher supply voltage can increase motor torque at higher speeds (>300 RPM), thus helpful for avoiding
losing steps. However, higher voltage may cause bigger motor vibration at lower speed, and it may also
cause over-voltage protection or even drive damage.
