■Warning and Caution:
Warning
Do not proceed to the assembly of the line while electrifying.
Circuit & change components between entering shutting down the power supply and stopping
showing CHARGE LED light of the Servo driver.
The output of Servo drive [U, V, W] must NOT touch the AC power.
Motor over temperature protection is not provided.
Caution
Install the fan if the temperature around is too high while the Servo driver is installed in the
Control Board.
Do not proceed to the Anti-Pressure-Test to the Servo driver.
Confirm the quick stop function is available before operate servo drive.
Matching up machine to change the user parameter setting before machine performs. If there is
no according correct setting number, it could lead to out of control or breakdown.
Safety proceeding:
Check the covering letter detail before installing, running, maintaining and examining. Furthermore, only
the profession-qualified people can proceed to the line-assembly.
Safety proceeding in the covering letter discriminate between “Warning” &”Caution.”
Indicate the possibility dangerous situation. It could cause the death or serious damage
if being ignored.
Indicate the possibility dangerous situation. It could cause smaller or lighter human
injured and damage of equipment.
Read this covering letter detail before using Servo driver.

First of all, thank you for using TECO Servo Driver JSDAP Series (“JSDAP” for short) and Servo Motors.
JSDAP can be controlled by digital board or PC, and provide excellent performance for a wide range of
applications and different requirement from customers.
Read this covering letter before using JSDAP. Contents of the letter comprise:
Servo System checking, installing and procedure of assembly line.
Controller procedure for digital board, status displaying, unusual alarm and strategy explanation.
Servo System control function, running testing and procedures adjusted.
Explanation for all parameter of Servo Driver.
Standard specification of JSDAP Series.
In order to daily examine, maintain and understand the reason of unusual situation and handle strategy,
please put this covering letter in safe place to read it anytime.
P.S: The end user should own this covering letter, in order to make the Servo Driver bring the best
performance.

Chapter 1 Checking and Installing
1-1 Checking Products
Our Servo Pack has already completely been functionally examined before leaving the factory. In
order to protect the products from the damage during transportation, please check the items below before
sealing off the pack:
Check if the models of servo driver and motor are the same with the models of ordering.
(About the model explanation, please check the chapters below)
Check if there are damage or scrape out side of the servo driver and motor.
(If there is any damage during transportation, do not power ON)
Check if there are any bad assembly or slipped component in the Servo Drive and Motor
Check if the Motor’s rotor and shaft can be rotated smoothly by hand
(The Servo Motor with Mechanical-Brake can not be rotated directly)
There must be the “QC”-seal in each servo drive, if not, please do not proceed Power ON.
If there is any bug or irregular under the situation above, please contact TECO’s Local sales representative
or distributor instantly.

1-2 A Brief Introduction of Operation for Drives
There are many kinds of control-mode. The detail modes display as the followings:
Name Mode Explanation
Single
Mode
Position Mode
(External Pulse
Command)
Pe Position control for the servo motor is achieved via an external
pulse command. Position command is input from CN1.
Position Mode
(Internal Position
Command)
Pi
Position control for the servo motor is achieved via by 16
commands stored within the servo controller. Execution of the
16 positions is via Digital Input signals.
Speed Mode S
Speed control for the servo motor can be achieved via
parameters set within the controller or from an external analog
-10 ~ +10 Vdc command. Control of the internal speed
parameters is via the Digital Inputs. A maximum of three steps
speed can be stored internally.
Torque Mode T
Torque control for the servo motor can be achieved via
parameters set or from an external analog -10 ~ +10 Vdc
command.
Tool turret Mode Pt The tool turret Mode use internal position command to do the
DI/DO switch to change the tool turret.
Multiple Mode
Pe-S Pe and S can be switched by digital-input-contact-point.
Pe-T Pe and T can be switched by digital-input-contact-point.
Pi-S Pi and S can be switched by digital-input-contact-point.
Pi-T Pi and T can be switched by digital-input-contact-point.
S-T S and T can be switched by digital-input-contact-point.
Pe-Pi Pe and Pi can be switched by digital-input-contact-point.

1-3 Conditions for Installation of Drives
1-3-1 Environmental Conditions
The product should be kept in the shipping carton before installation. In order to retain the warranty
coverage, the AC drive should be stored properly when it is not to be used for an extended period of time.
Some storage suggestions are:
Ambient Temperature: 0 ~ + 55 ℃; Ambient Humidity: Under 90% RH (Under the condition of no
moisture).
Stored Temperature: - 20 ~ + 65 ℃; Stored Humidity: Under 90%RH (Under the condition of no
moisture).
Vibrating: Under 0.5 G.
Do not mount the servo drive or motor in a location where temperatures and humidity will exceed
specification.
To avoid the insolation.
To avoid the erosion of grease and salt.
To avoid the corrosive gases and liquids.
To avoid the invading of airborne dust or metallic particles.
When over 1 Drives are installed in control panel, enough space have to be kept to get enough air to
prevent the heat; the fan also must be installed, to keep the ambient temperature under 55 ℃.
Please Install the drive in a vertical position, face to the front, in order to prevent the heat.
To avoid the metal parts or other unnecessary things falling into the drive when installing.
The drive must be stable by M5 screws.
When there were the vibrating items nearby, please using vibration-absorber or installing anti-vibration-
rubber, if the vibration cannot be avoided.
When there is any big-size magnetic switch, welding machines or other source of interference. Please
install the filter. When the filter is installed, we must install the insulation transformer.
