Yaskawa 2.0KW Servopack Drives-AC Servo Input 200/230 VAC SGDB-20ADM

u Installation Environment
n Enclosure Panels
Keep the drive in a clean environment by either selecting an area free of airborne dust, lint, and oil mist, or install the drive
in an enclosure panel. Be sure to leave the required space between drives to provide for cooling, and that proper measures are
taken so that the ambient temperature remains within allowable limits. Keep flammable materials away from the drive. If the
drive must be used in an area where it is subjected to oil mist and excessive vibration, protective designs are available. Contact
Yaskawa or your Yaskawa agent for details.
n Installation Direction
The drive should be installed upright as specified in the manual.
u Settings
n Motor Code
If using OLV/PM designed for permanent magnet motors (A1-02 = 5), make sure that the proper motor code is set in parameter
E5-01 before performing a trial run.
n Upper Limits
The drive is capable of running the motor up to 400 Hz. Due to the danger of accidentally operating the motor at high speed,
be sure to set the upper frequency limit. The default setting for the maximum output frequency is 60 Hz.
n DC Injection Braking
Motor overheat can result if there is too much current used during DC Injection Braking, or if the DC Injection Braking time
is too long.
n Acceleration/Deceleration Times
Acceleration and deceleration times are affected by how much torque the motor generates, the load torque, and the inertia
moment ((GD2
)/4). Set a longer accel/decel time when Stall Prevention is enabled. The accel/decel times are lengthened for
as long as the Stall Prevention function is operating. For faster acceleration and deceleration, install a braking option or increase
the capacity of the drive.
u General Handling
NOTICE: Wiring Check. Never connect the power supply lines to output terminals U/T1, V/T2, or W/T3. Doing so will destroy the drive. Be
sure to perform a final check of all control wiring and other connections before applying line power. Make sure there are no short circuits on
the control terminals (+V, AC, etc.), as this could damage the drive.
n Selecting a Molded Case Circuit Breaker (MCCB) or Ground Fault Circuit Interrupter (GFCI)
Yaskawa recommends installing a GFCI on the line power supply to protect drive wiring and prevent damage in the event of
component failure. An MCCB may also be used if permitted by the power system.
The GFCI should be designed for use with an AC drive (i.e., protected against harmonics)
MCCB selection depends on the power factor for the drive, determined by the power supply voltage, output frequency, and
load.
Refer to Installing Peripheral Devices on page 330 for more information on breaker installation. Note that a larger capacity
breaker is needed when using a fully electromagnetic MCCB, as operation characteristics vary with harmonic current.
n Magnetic Contactor (MC) Installation
Use an MC to ensure that line power to the drive can be completely shut off when necessary. The MC should be wired so that
it opens when the drive fault output is triggered.
Avoid switching the MC on the power supply side more frequently than once every 30 minutes. Frequent switching can cause
damage to the drive.
