- Page 6 6. Connections to Controller The 3P90M can accept differential and single-ended input signals (including open-collector and PNP output). The 3P90M has 3 optically isolated logic inputs which are located on connector P1 to accept line driver control signals. These inputs are isolated to minimize or eliminate electrical noises coupled onto the drive control signals.

8. Power Supply Selection The 3P90M can match large and medium size stepping motors (from NEMA size 34 to 43) made by I.CH Motion or other motor manufactures around the world. To achieve 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). - Page 8 Selecting Supply Voltage The 3P90M can actually operate within 90～150VAC or 126～210VDC, including power input fluctuation and back EMF voltage generated by motor coils during motor shaft deceleration. Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps.

Page 10: Wiring Notes
Standstill Current The 3P90M has automatic idle-current reduction function. The current automatically be reduced to 60% of the selected dynamic current setting 0.2 second after the last pulse. Theoretically, this will reduce motor heating to 36% (due to P=I2*R) of the original value. If the application needs a different standstill current, please contact I.CH Motion. -

Page 12: Protection Functions
Attention: Since there is no protection against power leads (+, -) reversal, it is critical to make sure that power supply leads correctly connected to the driver. Otherwise, the driver will be damaged instantly. Page 12 ©I.CH Motion® 2020 ichmo .com Specifications subject to change without notice. Owner's Guide: 3P90M Hybrid Stepper Motor Driver... -
Page 13: Frequently Asked Questions
14. Frequently Asked Questions In the event that your 3P90M doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently.
