1.Safety and assembly rules
1.1.Safety rules
Prior to first start-up of the device please refer to this manual;
Prior to first start-up of the device please make sure all cables are correctly connected,
Provide appropriate working conditions, in compliance with the device specifications (e.g.:
power supply voltage, temperature, maximum current consumption).
Before making any modifications to wiring connections, disconnect the power supply voltage.
1.2 Assembly recommendation
In environments with unknown noise levels, it is recommended to follow measures described below
to prevent any possible interruptions of the device operation:
Ground or reset metal rails, on which are mounted instruments,
Do not power devices on the same line as the device without a corresponding high power
line filters;
Please use screening of the supply, sensor and signal cables, with the ground for the screen
should be connected only on one side, as close to the device;
For motor power supply please use twisted pair cables, and if possible use a ferrite bead
assumed on the wire;
Please avoid of leading control cables (Signal) parallel or in close to electrical and power
wires;
Please avoid proximity to devices that generate high levels of electromagnetic interferences
and/or pulse (high-power loads, the burden of the phase or power control group).
2.Main characteristic of the driver
Miniature SMC64v2 driver is designed for use with 2-phase stepper motor with bipolar winding (8 or
4 wires) or unipolar 6-wires used as bipolar. It enables controlling with full step or step division on
2/4/5/8/10 or 16 parts. Rated current of motor is set by miniature switches in range of 1,2 –3,5A. At
decreased current consumption mode (up to 50%) occurs fading of clock pulses (automatically
reduction after 0,5 sec). SMC64v2 driver has active cooling as radiator with cooler (C) and is designed
for mounting on a mounting rail. For installation in the device is provided version(B) with the angular
radiator with aluminum sheet (2mm thickness). The controller has built-in generator, which allows
programming of two motor velocities. Additionally jumper allows for turn on function “SOFTSTART”,
which gently accelerate motor up to selected velocity.
2.1Features:
microprocessor, integrated power stages for 2-phase bipolar motors,
Thermal, voltage and short –circuit protection (partly, do not protect against short-circuit for
power supply an between phases),
High rated current 3,5A (4A temp)

Full, half step and microstep operation (1/4, 1/5, 1/8, 1/10, 1/16),
Two programmable timing frequency,
Soft start and return function,
Analog input 0-5V for generate velocity,
Opto- isolated output and input signals,
Severable automatic current reduction,
Power supply, signals for motor and controlling on separable rails Combicon type.
2.2. Power supply
The driver must be supply from source with proper output voltage (max. 40V) and current efficiency.
The feeder also must receive motor braking energy, which is provided by initial capacitors with
capacity at least 4700µF. It is recommended to use (dedicated for drivers) ZN100 feeder for small
motors and ZN200 feeder for large motors.
CAUTION!
Do not exceed maximal power supply of the driver, it can cause its damage.
2.3. Connection with a motor
To minimize disturbance caused by way of drivers work (current regulation by width, filling) cables,
which derivate signals to motor phases should be twist in pairs (A with /A, B with /B). Additionally it
is recommended to mount a ferrite bead on a cable.

3.2. Selection of motor current
Selection of motor current is made by SW switch according to the table below:
3.3. Operating modes of the driver
SMC64 v2 driver can operate in three operating modes:
1. Basic mode –external step (CLK) signal should be applied into CLK+ and CLK- inputs. Maximal
frequency on driver output is up to 60 kHz. Above this frequency it is not guarantee correct
operation of the driver.
2. Selected V1/V2 speed mode –driver enables selecting one of preset frequencies, which are
selected by V1 and V2 jumpers. Then is not necessary to give external CLK signals, the driver
produce clock signal by its own.
3. 0…5V intput mode (Ain) – at this mode is possible to set frequency for internal generator by
changing voltage value on Ain input (J6).
Particular operating modes are further described in details.

3.3.1.Selected V1/V2 speed mode
The driver can operate in constant timing frequency, after selecting it by V1 and V2 jumpers on J3
connector pin, according to a scheme below:
Prior to selecting velocity it should be programmed at first. Programmed frequency is store at non-
volatile memory of the driver, due this it is accessible also after turn on and turn off of driver power
supply. After programming the velocity is set, when on CLK input is set a high state.
3.3.1.1. Procedure of programming V1 and V2 velocity
Both to V1 and to V2 can be subordinate one of following, automatically generated frequencies (Hz):
Order of V1 (V2) frequency programming actions:
1) Turn off driver power supply
2) Give EN permission signal (5 and 6 clamps of J2 connector),
3) Short -circuit V1 and V2 pins by jumpers,
4) Turn on driver power supply –motor should start rotate with rising velocity every 0,5s
according to table above,
5) At the moment of reaching proper velocity took off the V1 (V2) jumper, and then V2 (V1)
6) Turn off power supply.
The procedure above assume non active clock input (CLK)
There is also a possibility of programming as V1 and V2 frequencies given from external generator.
Therefore turn off a permission signal (EN non active), and on CLK input (1 and 2 clamps of J2
connector) give signal with required frequency, and made all actions from 4 to 6 of procedure above.
In this case it is impossible to observe motor work.

3.3.2. 0…5V intput mode (Ain)
This mode enables setting velocity by analog input Ain (J6).
Analog signal should be connected to J6 connector. A potentiometer also can be connected,
according to picture below.
Procedure of activation Ain input:
1) Turn off driver power supply
2) Put AN jumper
3) Turn of driver power supply
From this moment frequency of driver internal generator is proportional to voltage given on Ain
input according to formula:
Fgen(Hz)=Ain*204,8
Where for voltage <0,1V Fgen =0 (motor is stopped)
Additionally by V1 and V2 jumpers can be calibrated generator frequency.
CAUTION!
On Ain input can be given voltage from range 0..5V. Do not exceed this range.
