2.1.2 Installation Environment and Precautions
a) Environment temperature: the surrounding environment temperature has a great impact on the lifespan of the spindle servo drive, so it must
not exceed the allowable temperature range (-10℃~50℃), and when the environment temperature exceeds 40℃, the external forced heat
dissipation and the drive must be derated to use.
b) Humidity should be below 95% and no condensation of water droplets at the site. Avoid applications with direct sunlight, oil, dust or metal
dust.
c) Thin air above 1000m will lead to poor heat dissipation, so please derate to use it. Derate by 1% for every 100m of elevation.

SD500 Spindle Servo Drive Manual
8
d) The spindle drive needs to be mounted on a flame-retardant surface to ensure enough space for heat dissipation. The mounting surface needs
reliably bear the weight of the spindle servo drive, otherwise there is a possibility of personnel injury or equipment damage if it falls.
e) When the spindle drive is installed near a vibration source, please install vibration isolators on the mounting surface of the servo unit to
prevent vibration from being transmitted to the servo unit.
f) Install the spindle servo drive away from sources of electromagnetic interference.
2.1.3 Spindle Drive Installation Space Requirements
Heat generated from SD500 spindle servo drive is distributed in a bottom-up way, the spindle servo drive must be installed in the following
vertical way (see Figure 2-1), and other components in the cabinet should be taken consideration to ensure that the SD500 spindle drive has
enough space for heat dissipation. Multiple spindle servo drives are usually installed side by side, and the installation space requirements are
shown in the figure below as well. In cases where the drives are mounted above or below, it is highly recommended to install thermal deflectors
between the drives.

Selected according to 100% of the rated current of the drive.
Braking resistor
Models with 37kW and below
For models with 37kW or lower, please use the optional braking resistor, and
refer to the braking resistor matching table;
The motor consumes regenerative energy through the braking resistor during
decelerating.
Table 2-1
⚫select braking resistor
When the spindle drive with large inertia decelerates with load or for emergency, the motor is running under the discharge state, the load
energy through the inverter bridge to the spindle drive DC link, causing the spindle drive bus voltage to rise until it exceeds a certain limit, and
then the drive will report an overvoltage fault, to prevent which, those external braking components need to be installed. The following table
shows the typical reference values of external braking resistor specifications:

The table is a typical reference data, the braking resistor needs to be determined according to the power generated by the motor in the
actual application system (but the braking resistance value cannot be lower than the limit in the table above), and the system inertia, deceleration
time, the energy of the bit energy load, etc. are related. The greater the inertia of the system, the shorter the deceleration time required, and the
more frequent the braking, the greater the power and the smaller the resistance value of the braking resistor needs to be. Users can choose
different resistor resistance and power according to the actual situations, please consult our technical support for detailed calculation.

2.2.6 Control Circuit Wiring Instructions
◆AI analog input circuit:
SD500 spindle servo provides two analog input interfaces AI1 (-10~+10V) and AI2 (0~+10V or 0~20mA). Since the weak analog signals
are susceptible to external interference, the wiring control cables should be sufficiently far away from the main circuit and strong power cables
(including power cables, motor cables, relays, contactor connection cables, etc.) for more than 30cm and avoid parallel placement. The
connection cable is strongly recommended to use twisted shielded pair cables, and the cable shielding layer should be reliably connected to the
drive terminal housing, and the wiring distance should be as short as possible. In some cases where the analog signal is subject to serious
interference, a ferrite magnet ring can be added near the driver end. The following diagram shows the analog input terminal wiring diagram:

◆Digital input terminal wiring:
The digital input terminals X1 to X7 support either drain or source wiring. The following is an example of X1, and interface circuit for X1
to X7 are all the same. The following is an example of wiring through a relay or transistor circuit (drain or source wiring). When using a relay
connection, select a relay for microcurrent. If there is no such a relay for microcurrent, it may cause poor contact.
