1Introduction
Thank you for selecting a MOONS' motor drive. We hope our dedication to performance,
quality and economy will make your motion control project successful.
If there’s anything we can do to improve our products or help you use them better, please call
(86)21-52634688 or fax [phone]. You can also email [email protected].
1.1 Overview
The SR series drive is one cost-effective, high performance 2 phase stepping drive, designing
based on the AC servo drive technology, with high torque, low noise, and low vibration. You
can select the running current and microstep resolution by a piano switch. Our purpose is to
have a drive which is cheaper but with better performance, especially for low cost and high
quality market.

4Connecting
To use the drive models of SR4 and SR8,
you should have the following:
A power supply (24-48VDC for SR4
and 24-75VDC for SR8)
Pulse & Direction signal
A compatible stepping motor
4.1 Connecting to Power Supply
If your power supply does not have a fuse on the output or some kind of short circuit current limiting device
you need to put a fast acting fuse(Current ratings never exceed 10 Amps) between the drive and power
supply. Install the fuse on the + power supply lead in series.
Connect the motor power supply "+" terminal to the drive terminal labeled " V+". Connect
power supply "-" to the drive terminal labeled " V-".
Be careful not to reverse the wires.

4.3 Connecting to Inputs
4.3.1 Pulse & Direction inputs
The SR Drive has two high speed optically isolated inputs called STEP and DIR. They accept
the 5 to 24 Volts single-ended or differential signals, which up to 2MHz. The max voltage that
can be applied to the input is 28V.
The motor executes one step with the falling edge of the STEP signal.
The direction of rotation is controlled by the DIR signal level. The low signal (0 level) is
clockwise rotation, and the high signal (1 level) is Counterclockwise rotation.
4.3.2 EN input
The EN input enable or disable the drive amplifier. It is an optically isolated input that accepts
5 to 24 Volts single-ended or differential signal. The max voltage that can be applied to the
input is 28V.
When EN input is closed, the driver amplifier is deactivated. All the MOSFETs will shutdown,
and the motor is free. When EN input is open, the drive is activated.
When drive is in Error status and the fault is removed from system, one falling signal into EN
will reset error status and activate driver amplifier again.
4.3.3 Connecting Circuit
Connecting to control with Sinking outputs.
Connecting to control with Sourcing outputs.

Connecting to control with Differential outputs.
Fault Output
The FAULT Output is optically isolated. The Max collector current is 100mA, and the Max
Collector to Emitter voltage is 30 V. The Output can be wired to sink or source current.
When driver works normally, the output is open. And when driver has error, the
output is closed.
4.3.4 Error Code
Status LED
The SR Drive include two (red/green)LEDs to indicate status.Normal status is indicated by a
green LED.If the red LED flashs,an error has occurred.The errors are indicated by
combinations of red and green “flashes” as follows:
z Solid green Motor disabled
zz Flashing green Motor enable
zzzzz 3 red, 2 green Internal Voltage Bad
zzzzz 4 red, 1 green Over Voltage
zzzzzz 4 red, 2 green Under Voltage
zzzzzz 5 red, 1 green Over current/Short circuit

value can be changed to meet the customers’ needs.

7.8A OFF OFF OFF
5.2 Idle Current
Your drive is equipped with a feature that automatically reduces the motor running current
by 50% anytime the motor needn’t moving. This feature can be disabled if desired so that
90% running current is maintained when motor need not move. This is useful when a high
holding torque is required. To minimize motor and drive heating we highly recommend that
you enable the idle current reduction feature unless your application strictly forbids it.
5.3 Microstepping
SR Drive set the Microstep resolution by the SW5, SW6 and SW7.There are 8 setting.

5.4 self test
Setting the SW8 to “ON” after the drive is powered up, will cause the drive to perform a “Self
Test” of 2 rev move both CW and CCW at 1rps.

6Motor select
The 16-bits Rotary switch will select different motor, and automatically set the different
configuration parameters into the drive. MOONS’ can choose up to 8 typical motors as their
factory default motor selections. Custom drives can have motors that are special for a given
customer.
The Rotary switch will be able to select the low or high inertia for different load. Low setting will
be 1:1; high setting will be 10:1. Each given motor in the loaded database will have unique
settings to optimize the Anti-resonance. See “Typical Motors” table below.
If you change the motor selecting, please recycle the drive power supply.

7Drive Mounting
7.1 Mechanical Outline
Unit:mm
7.2 Mounting the Drive
You can mount your drive on the wide or the narrow side of the chassis. If you mount the
drive on the wide side, use M3 screws through the four corner holes. For narrow side
mounting applications, you can use M3 screws in the two side holes.
The amplifiers in the drive generate heat. To operate the drive continuously at maximum
power you should take compulsory air-cooled method。
Never use your drive in a space where there is no air flow or where other devices cause the
surrounding air to be more than 40 °C. Never put the drive where it can get wet or where
metal particles can get on it.
