Suppose a client wants to drive four 1.2kW motors with 1kW*4 Servo Drive
Embedded Controller, it means the gross power should supply at most 4.8kW. Then
we reverse the formula and set the power factor at 0.7. If only Servo Drive Embedded
Controllers are used, the capacity should be at least 4.8/0.7=6.85kVA. In addition,
10% of the backup capacity should be considered. Thus, 7.5kVA would be more
suitable. Moreover, if an inverter is used, and the power is supplied by an isolation
transformer, the capacity of the inverter should be considered.
Do not connect a cable with other cables to extend the length. It might cause signal
error or malfunction.
Please crimp or weld the wire connections while doing the wirings.
If the servo line in use is not a standard Syntec cable, please verify all the terminals
connected properly before power-on. Wrong wirings will lead to controller output
command errors and malfunctioning.
The +5V output capacity of the encoder is 500mA and is only for a single encoder.
Do not connect it with other loads or it might cause error due to the lack of driving
force.
Do not use counterfeit terminal strips. Those terminal strips cannot provide overall
protection for the system. The quality is also not guaranteed and tend to cause
electrical control problems of the machine tools.
The wiring of the driver and the motor cannot be pulled too tightly.
Do not stake on top.
The six power lines, R, S, T and U, V, W, should not be close to other signal lines,
and should be at least 30 cm apart.
After cutting off the power, the capacitor of the driver still contains large amount of
charge. Do not touch the 6 power lines, R, S, T and U, V, W, until the power
indicator goes out.
If the encoder line should be longer, please use twisted-pair and signal cable with
isolated ground. Do not extend it over 20 meters. In case of extensions over 20
meters, please double the wire diameter of signal cables to reduce signal attenuation.
To ensure the quality of communication, the USB extension cord in use should not
exceed 5 meters, and do not use for charging purposes to avoid controller failure.
The drive is fragile. Please handle it with care.
Do not allow conductive foreign matter such as screws or metal chips, or combustible
foreign matter such as oil enter the driver.
Applicable motors: Please refer to the selection manual.
Please comply with the wire gauge standards. The recommended wire diameter varies
with the motor wattage. Please refer to the table below:
Type
Wattage
Wire Diameter
Axial
100W~850W
20AWG
850W~7.5kW
16AWG
Spindle
Less than 7.5kW (Include)
12AWG
More than11kW (Include)
10AWG
Please connect the ground wire to class-
3 (under 100Ω). Poor grounding might cause
signal error, electric shock, or fire.
The grounding of the motor must be connected to one of the grounding terminals of
the frequency converter.
In accordance with EN 61800-5-1 (Section 4.3.5.5.2), since the normal contact
current of the frequency converter is higher than 3.5 mA AC or 10 mA DC, a fixed
protective earthing connection must be used:
1) The cross-sectional area of the protective earthing wire should be coper wires of
at least 10mm
2
or aluminum wires of at least 16 mm
2
.
2) Automatically cut off the power when the protective earthing conductor is
interrupted.
3) Replace the original protective earthing conductor with a spare one that has the
same cross-sectional area.
⚫
Grounding Directions:
1) The length of grounding wires should comply with the electrical equipment
regulations; the shorter the better.
2) The grounding wire of the driver should be grounded separately with
high-current loads such as electric welders or high frequency motors.
3) Please refer to the pictures below when the controller is grounded with multiple
electrical control devices. Do not make it a loop
