Read this manual carefully before trying to install the stepper drive into your system. The person setup the stepper drive should have a better understanding on electronics and mechanics. Contact Leadshine technical guys when have questions on this document. Notice Make sure the power supply voltage dose not exceed the drive’s input range.
They are capable of delivering high performance without damages to your machines or the materials. Leadshine EM series stepper drives are able to drive 2-phase stepper motors from NEMA8 to NEMA42.
EM Series Drive Hardware Installation Manual Elimination of Heat Drive’s reliable working temperature(heat sink) should be <70 (158℉), and motor working temperature(surface) should be <80℃ (176℉); It is recommended to use automatic idle-current mode, namely current automatically reduce to 60% when motor stops, so as to reduce driver heating and motor heating;...
EM Series Drive Hardware Installation Manual 4. Control Signal Requirement Signal Mode and Sequence Chart Most EM drive can support Pulse/Direction and CW/CCW control signal modes. In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram: Remark: ENA must be ahead of DIR by at least 5us.
EM Series Drive Hardware Installation Manual 5. Connecting Control Signal Most of the EM stepper drives can accept both differential and single-ended inputs (including open-collector and PNP output). Some only accept the single-ended inputs due to space limit NPN Signal Connections...
EM Series Drive Hardware Installation Manual 6. Connecting the Motor The EM drive can drive any 2-pahse and 3-phase hybrid stepper motors. 2-phase, 4-lead Motors Connections 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance. In setting the drive output current, multiply the specified phase current by 1.4 to determine the peak output current.
EM Series Drive Hardware Installation Manual 2 phase, 8-lead Motors Connections 8 lead motors offer a high degree of flexibility to the system designer in that they may be connected in series or parallel, thus satisfying a wide range of applications.
7. Power Supply Selection The DM drive can match medium and small size stepping motors (from NEMA frame size 8 to 34) made by Leadshine or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly.
EM Series Drive Hardware Installation Manual Recommended Supply Voltage The following table gives the recommended supply voltage for different drives. Model Voltage Range Typical Voltage Leadshine Power Supply DC(20-36)V DC 24V RPS2410(-L) EM402 DC(20-45)V DC 36V RPS369 EM503 EM705 DC(20-63)V...
EM Series Drive Hardware Installation Manual 9. Wiring Notes In order to improve anti-interference performance of the drive, it is recommended to use twisted pair shield cable. To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should not be tied up together. It is better to separate them by at least 10 cm, otherwise the disturbing signals generated by motor will easily disturb pulse direction signals, causing motor position error, system instability and other failures.
Active Edge Configuration Procedure If it is the first time installation and the EM drive works together with pre-matching Leadshine stepper motor, you can follow the steps below to configure the EM series stepper drive: Set the rotation switch according to the motor...
Auto Configuration If a non-Leadshine stepper motor is used in your system, switch SW3 (EM402) or SW4 (others) two times in one second to activate Auto-configuration for optimized performance if it is first time installation. Make sure the motor selection switch is set to one of the custom motor position.
When power supply voltage exceeds the limit, protection will be activated and red LED will blink twice within each periodic time. Sensorless Stall Detection By detecting motor voltage, current, and back-EMF signal, EM series drives can detect loss-of-synchronization of stepper motors without encoders. When the detection is activated, red LED will blink five times within each periodic time.
EM Series Drive Hardware Installation Manual Note: When above protections are active, the motor shaft will be free or the LED will blink. Reset the drive by repowering it to make it function properly after removing above problems. For sensorless stall protection, you can also clear the error in ProTuner. See drive’s software operational manual for more information.
