4 Transportationand Installation
4.1 Transportation
The entire body of the drive must be held during transportation. To avoid the risk of falling, do NOT hold the drive
by its upper cover or by any individual part.
4.2 Installation Environment Conditions and Precautions
Installation Environment Conditions
Locations without high heat generating devices.
Locations without floating dust or metal particles.
Locations without corrosive or flammable gasses and liquids.
Locations without water, steam, dust, or oily dust.
Locations without electromagnetic noise interference.
A sturdy, vibration-free location.
Suitable ambient temperature is 0 ° C ~ 55 ° C; if the ambient temperature is above 45 ° C, please put the
drive in a well-ventilated place or in an air-conditioned room.
Installation Precautions
Install the drive in the direction specified bythe instructions; incorrect positioning may lead to servo failure.
When installing the drive, do not block its ventilation holes and do not place it upside down, otherwise the
drive may malfunction.
Do not use on or near flammable materials.
Make sure that each fastening point is tight when fixing the drive in place.
Install on a surface that can withstandthe weight.
Operation Precautions
For long-term operation, it is recommended to maintain an ambienttemperaturebelow 45 °C to ensure
product reliability.
If the product is installed inanelectrical cabinet, the size and ventilation of thecabinetmust prevent any
internal electronic devices from overheating. Also pay attention to whether the machine's vibrations will
affect other electronics in the cabinet.
To enhancecooling circulation, maintain sufficient space between all sides and surrounding objects of the
drive and the baffles (walls); also take care not to block the ventilation holes, otherwise the drive may
malfunction.
Other Precautions
The cable between the drive and the motor should not be stretched too tightly.
Do not place heavy objects on top of the drive.
Keep the drive clear from conductive objects such as metal and screws or combustibles such as oil.
If the cable connecting the motor and the drive is longer than 20 meters, please thicken the U, V, W and
encoder cables.

SPD-32C1-075
Installation Precautions:
Before powering on, please check again whether the U, V, W, G terminals of the output to the motor
are connected correctly through the wire markers. If the UVW three-phase connection is reversed, it
may cause reversal or abnormality, and the encoder function test and magnetic pole angle detection
must be performed again. If G is connected incorrectly, it may cause damage to the motor or driver.
The power supply of the control board is recommended to be directly supplied by any two of the three
RST terminals.
When wiring the host controller, only one of the general-purpose servo signal and the serial servo
signal can be installed.

Wiring Precautions:
Keep the six power lines R, S, T and U, V, W away from other signal lines, at least a 30 cm distance if possible.
When the power is cut off, the drive's internal capacitor still contains a large amount of charge--do NOT
touch the six power lines R, S, T, and U, V, W. Please wait until the charging light goes out.
When lengthening the encoder cable, apply twisted pair cabling to the encoder cable and the grounding
signal cable. Do not exceed a length of 20 m (65.62 in or 14 ft); if it is absolutely necessary to do so, please use
a signal line with twice the wire diameter in order to minimize signal attenuation.
Please wire according to relevant regulations. Select the wire diameter according to motor wattage, as
follows:

5.6 Regenerator Selection
5.6.1 Simple regenerator selection
The recommended capacity of Syntec regenerator is listed in the table below:
Drive model Recommended capacity
(Note 1)
Recommended Resistor Value
(This value is the minimum value, refer to
Note 2)
SPD-32E1-050 1000 W 30 Ω
Note:
The Recommended Regeneration Resistance Table is designed for general machining situations. If these
values do no meet the actual application conditions, users can refer to the Detailed Selection Guide for
Regenerative Resistors and select a regenerator of higher power.
Recommended resistance = operating voltage / maximum brake current, and it is the minimum regenerative
resistanceofthe drive. If no suitable resistance value is found, users must select a regenerator of higher
power.
There are three types of regenerative resistors commonly used in CNC machining: wirewound resistors,
rippleresistors, and aluminum-housed resistors; users can select the type according to their needs. The following
chart compares the three types of brake resistors:

Detailed Selection Guide for Regeneration Resistors
Motors do Negative Work under External Torque Load
Motors generally do positive work while operating, but they may do negative work when the output torque
direction is opposite of the rotation direction. For instance, the motor may output torque to resist the inertia during
braking, or it may experience an external torque load while in torque mode...etc. During those times, the external
force is doing positive work through the motor and transferring that energy to the drive; that is, the motor acts as a
generator. When this happens, the regenerative resistor must quickly dissipate the energy in order to prevent
flooding the DC terminal voltage.
Suppose the external torque load is TLand the unit is a percentage of the rated torque (%). The speed at that
instance in time is Wr (rpm). The regenerative resistance power must be greater than the External Torque Power =
TLx Rated Torque x (Wr x 2π/60).
For example, if the external torque is 50% of rated torque, the speed is 2000 (rpm), and the motor rated torque is
2 (Nm), then the external torque produces a power of 0.5 * 2 * 2000 * 2π/ 60 ≈210 W. To be safe, that number is
usually multiplied by a safety factor of around 2 ~ 3, therefore the user needs to select a regenerative resistor of
more than 420W.
Free of External Torque Load
Assuming that the motor moves back and forth, the energy generated by the inertial force during braking will be
poured back into the drive. At this time, the capacitor of the DC bus terminal of the drive is the first buffer to absorb
and reuse the energy. However, the absorption of energy by the capacitor causes the DC bus voltage to rise, so
伺服產品/Servo Products

Hardware Manual of 380V 7.5kW Servo Drive II (SPD-32C1-075)
Wiring and Signal–20
when the voltage rises to a certain level, the second buffered regenerative resistor is turned on to convert the
energy into heat and discharge it.
The calculation method of the regenerative energy generated by the spindle motor of the drive during braking is
provided below, and the user can calculate the required resistance according to different occasions.
E0in the table below is the regenerative energy required to dissipate from the rated speed to the standstill when
the motor is load-free, E0=J*ωr2/182, where J is the rotor inertia (kg-m2) and ωr is the rated speed of the motor
( Rpm). And Ec is the energy that the DC bus capacitor can absorb, Ec = C*(Vb,max2-Vb2)/2, where C is the capacitance
value of the DC bus terminal. Vb,maxis the maximum voltage that the DC bus can withstand, the 220V drive can
withstand 400 V, and the 380V drive can withstand 800 V. The Vbvalue is the rated voltage of the DC bus, and the
value is 2 times the root of the input supply voltage.
Considering the actual application, assume that the load inertia ratio is N times the motor inertia. If the speed is
braked from the rated M times to zero speed, the regenerative resistor must consume E0(N+1)*M2-EcJoule. If the
motor reciprocating cycle (Time of accelerating, being steady, to decelerating) is T sec, then the regenerative
resistor power W =1.2[E0*(N+1)*M2-Ec]/T, 1.2 is the safety factor.
In addition, according to the application of the spindle cover, the allowable frequency index is provided for the
user to select. The allowable frequency is defined as the continuous acceleration and deceleration of the motor. In
the case where the regenerative resistor and the motor are not overheated, the maximum number of round trips
per minute is equal to 60 seconds divided by the round trip period T, i.e. 60/T.For example, when the milling
machine is performing drilling and tapping, the spindle will frequently perform acceleration and deceleration
(single drilling involves two acceleration and deceleration actions). If it is desired that the regenerative resistor is
not prone to overheating and smoke, the number of drilling per minute must be limited to less than half of the
allowable frequency.
