Page 5: Overview
It is used for controlling standard stepper motors (including with attached encoders) or motors with an integrated encoder. BLDC motors are also supported. The SMCI36 is ideal for device installation due to its open, economical design and TTL signal level (5 V). For machine integration, we recommend the closed controllers SMCI33 and SMCI47-S-2, which can also process 24 V signals and are built on the same software basis. - Page 6 NanoCAN user manual. Presettings When the SMCI36 is delivered, it is preconfigured to relative positioning mode. The step mode can only be changed via software. It is preset to the half step setting. Due to microstep emulation, however, the stepper motor runs very smoothly and with excellent performance even in the half step.

The differential signal can be evaluated with a line driver/encoder adapter. Since the SMCI36 is designed for device installation, the differential signals are not evaluated so that only channels A, B and I need to be connected to perform position monitoring. -
Page 16: Motor And Power Supply Connection: Connector X3
3.4.2 Stepper motor connection General information The motor is connected to the SMCI36 with a 4-wire cable. Twisted wire pair cables with braided shields are recommended. Danger of electrical overvoltage Accidentally swapping the connections will destroy the output stage. See the data sheet of the connected stepper motor. -
Page 17: Power Supply Connection
Power supply connection Permissible operating voltage The permissible operating voltage for the SMCI36 lies between +12 and +72 V DC; it must not exceed 75 V or fall below 10 V. A charging capacitor with minimum 4700 µF (10000 µF) must be provided for the operating voltage to prevent exceeding the permissible operating voltage (e.g. -
