2.3 Mechanical Specification
(unit: mm [1inch=25.4mm])
Figure 1: Mechanical specifications
* Side mounting recommended for better heat dissipation
2.4 Elimination of Heating
EM522-CAN reliable working temperature should be < 60℃(140°F) and stepper motor should be <120℃(248°F)
It is recommended to use automatic idle-current mode to reduce drive and motor heating. That means output current will
be reduce to 50% when the motor at standstill.
It is recommended to mount the drive vertically to maximize heat sink area. Use forced cooling method to cool if
necessary.

Notice
Notes: (1) The EM522-CAN at the end of the network need to plug a terminal resistance in any one of the P3
interface(RJ45); (2) In order to avoid bad insulation performance as heating, cable and wire should be fixed well and keep
away from motors and drives.
4.3 Motor Connection
The EM522-CAN can drive 2-phase and 4-pahse bipolar hybrid stepper motors with 4, 6, or 8 wires (frame size from
NEMA17).
4.3.1 Connections of 4-lead Motor
The 4 lead motors are the least flexible and easy to connect. And the Speed – torque of motor depends on winding inductance.
The output current from drive that is multiply the specified phase current by 1.4 to determine the peak output current.

4.3.2 Connections of 6-lead Motor
Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operations. The
higher speed configuration, or half coil, is described, because it uses one half of the motor’s inductor windings. The higher
torque configuration, or full coil, uses the full coil windings.
(1) Half Coil Configuration
As previously stated, the half coil configuration uses 50% of the motor phase windings. This gives lower inductance, hence,
lower torque output. Like the parallel connection of 8 lead motor, the torque output will be more stable at higher speeds. This
configuration is also referred to as half chopper. In setting the drive output current multiply the specified per phase (or
unipolar) current rating by 1.4 to determine the peak output current.
Figure 5: 6-lead motor half coil (higher speed) connections
(2) Full Coil Configuration
The full coil configuration on a six lead motor should be used in applications where higher torque at lower speed is desired.
This configuration is also referred to as full copper. In full coil mode, the motors should be run at only 70% of their rated
current to prevent overheating.
Figure 6: 6-lead motor full coil (higher torque) connections
4.3.3 Connections of 8-lead Motor
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.
(1) Series Connection
A series motor configuration would typically be used in applications where a higher torque at lower speed is required.
Because this configuration has the most inductance, the performance will start to degrade at higher speed. In series mode, the
motors should also be run at only 70% of their rated current to prevent overheating.
Figure 7: 8-lead motor series connections

EM522-CAN Field bus Stepper Drive User Manual V1.0
10
(2) Parallel Connection
An 8 lead motor in a parallel configuration offers a more stable, but lower torque at lower speeds. But because of the lower
inductance, there will be higher torque at higher speeds. Multiply the phase (or unipolar) current rating by 1.96, or the bipolar
current rating by 1.4, to determine the peak output current.
Figure 8: 8-lead motor parallel connections
4.4 Power Supply Selection
The EM522-CAN can power medium and small size stepping motors (frame size from NEMA17 to 24) made by Leadshine
or other motor manufacturers. To get 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). Higher supply voltage will allow higher motor
speed to be achieved, at the price of more noise and heating. If the motion speed requirement is low, it’s better to use lower
supply voltage to decrease noise, heating and improve reliability.
4.4.1 Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the drive. However, unregulated power supplies are
preferred due to their ability to withstand current surge and fast response for current change. If you prefer to a regulated
power supply, it is suggested to choose such a power supply specially designed for stepper/servo controls such as Leadshine
RPS series (http://www.leadshine.com/producttypes.aspx?producttype=regulated-switching). Or, in the case when only
normal switching power supplies are available, it is important to use “OVERSIZE” high current output rating power supplies
(for example, using a 4A power supply for 3A stepper motor) to avoid problems such as current clamp. On the other hand, if
unregulated supply is used, one may use a power supply of lower current rating than that of motor (typically 50%~70% of
motor current). The reason is that the drive draws current from the power supply capacitor of the unregulated supply only
during the ON duration of the PWM cycle, but not during the OFF duration. Therefore, the average current withdrawn from
power supply is considerably less than motor current. For example, two 3A motors can be well supplied by one power supply
of 4A rating.
4.4.2 Power Supply Sharing
Multiple EM522-CAN drives can share one power supply to reduce cost, if that power supply has enough power capacity. To
avoid cross interference, connect each stepper drive directly to the shared power supply separately. To avoid cross
interference, DO NOT daisy-chain connect the power supply input pins of the Drivers. Instead connect them to power supply
separately.
4.4.3 Selecting Supply Voltage
The EM522-CAN is designed to operate within +20 - +50VDC voltage input. When selecting a power supply, besides
voltage from the power supply power line voltage fluctuation and back EMF voltage generated during motor deceleration
needs also to be taken into account. Ideally it is suggested to use a power supply with the output range of +24 - +48 VDC,
leaving room for power line voltage fluctuation and back-EMF.
Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. However, higher
voltage may cause bigger motor vibration at lower speed, and it may also cause over-voltage protection or even drive damage.

EM522-CAN Field bus Stepper Drive User Manual V1.0

Therefore, it is suggested to choose only sufficiently high supply voltage for intended applications.

When bit16 of 60FE+01and
60FE+02 are both "1",
OUTPUT1 have output
When bit17 of 60FE+01and
60FE+02 are both "1",
OUTPUT2 have output
and so on……
