1.4 Selection of other accessories
1.4.1 Selection of regenerative resistance
When the servo motor is driven by the generator mode, the power returns to the servo amplifier side,
which is called regenerative power. The regenerated power is absorbed by charging the smooth
capacitor of the servo amplifier. After exceeding the rechargeable energy, the regenerative resistance is
used to consume the regenerative power.
The servo motor driven by regenerative (generator) mode is as follows:
The deceleration stop period during acceleration and deceleration operation;
Running vertically and axially;
When the external load drives the motor to rotate.
Servo driver model
Regenerative resistance connection terminals
DS5□-P□-PTA
(1) Using built-in regenerative resistance, short P + and D terminals, P + and
C are disconnected.
(2) Use external regenerative resistance, connect regenerative resistance to P
+ and C terminals, remove P + and D short wiring, P0-25 = power value,
P0-26 = resistance value.
Note: if software version U2-07 < 3700, the parameter P0-24 should be set.
The value of 0 is for the built-in resistance to take effect, and the value of 1 is
for the external resistance to take effect.
It no needs to set P0-24 for the firmware version U2-07≥3700, just keep
default value.

The following table is the recommended specifications of external regenerative resistance for each type
of motor.

Note:
(1) The smaller the resistance is, the faster the discharge will be, but the smaller the resistance is, the
easier the breakdown resistance will be. Therefore, please close to the the lower limit but not be less
than the lower limit when choosing the type.
(2) When wiring, please use high-temperature flame-retardant wire, and the regenerative resistance
surface can not contact with the wire.

Be sure to comply with the installation standard in the control cabinet shown in the figure below. This
standard is applicable to the situation where multiple servo drivers are installed side by side in the
control cabinet (hereinafter referred to as "when installed side by side").
Servo Drive Orientation
Install the servo drive perpendicular to the wall so the front panel containing connectors faces outward.
Cooling
As shown in the figure above, allow sufficient space around each servo drive for cooling by cooling
fans or natural convection.
Side-by-side Installation
When install servo drives side by side as shown in the figure above, make at least 10mm between and
at least 50mm above and below each servo drive. Install cooling fans above the servo drives to avoid
excessive temperature rise and to maintain even temperature inside the control panel.

Humidity: 90%RH or less

Vibration: 4.9m/s2
Condensation and Freezing: None
Ambient Temperature for Long-term Reliability: 50°C maximum
2.2 Servo motor installation
MS series servomotors can be installed either horizontally or vertically. The service life of the
servomotor can be shortened or unexpected problems might occur if it is installed incorrectly or in an
inappropriate location. Follow these installation instructions carefully.
CAUTION
1．The end of the motor shaft is coated with antirust. Before installing, carefully remove all of the
paint using a cloth moistened with paint thinner.
2．Avoid getting thinner on other parts of the servo motor.
2.2.1 Environment condition
When used in places with water droplets or oil droplets, the protection effect can be achieved through
the treatment of motors. However, in order to seal the through part of the shaft, please specify the
motor with oil seal. Connectors should be installed downward.
MS series servo motors are for indoor use. Please use them under the following installation conditions:

2.2.2 Installation cautions
Item
Description
Antirust treatment
◆Before installation, please wipe the "rust-proof agent" of the extension end
of the servo motor shaft, and then do the relevant rust-proof treatment.
Encoder cautions
◆It is forbidden to impact the extension end of the shaft during installation,
otherwise the internal encoder will be broken.
◆When the pulley is installed on the servo motor shaft with keyway, the
screw hole is used at the end of the shaft. In order to install the pulley, the
double-headed nails are inserted into the screw holes of the shaft, the washer is
used on the surface of the coupling end, and the pulley is gradually locked with
the nut.
◆For the servo motor shaft with keyway, use the screw hole at the end of the
shaft to install. For shaft without keyway, friction coupling or similar methods
are used.
◆When the pulley is dismantled, the pulley mover is used to prevent the
bearing from being strongly impacted by the load.
◆To ensure safety, protective covers or similar devices, such as pulleys
installed on shaft, are installed in the rotating area.
Centering
◆When installing the servo motor, make it conform to the centering accuracy
requirement shown in the picture below. If the centering is inadequate, vibration
will occur, and sometimes the bearing and encoder may be damaged. When
installing the coupling, please do not directly impact the motor shaft, otherwise
the encoder installed on the opposite side of the load shaft will be damaged.
Installation
direction
◆Servo motor can be installed in horizontal or vertical direction.
The maximum and minimum deviations are
less than 0.03mm (rotated with the coupling)
measured at four locations in a circle.
