P9 ASD Quick Start Guide
Installation and Connections
The
P9 True Torque Control
2
Adjustable Speed Drive
may be set up initially by performing a few
simple configuration settings. To operate properly, the ASD must be securely mounted and connected to
a power source (3-phase AC input at the R/L1, S/L2, and T/L3 terminals). The control terminals of the
ASD may be used by connecting the terminals of the
Terminal Board
to the proper sensors or signal
input sources (See the section titled
).
System performance may be further enhanced by assigning a function to the output terminals of the
Terminal Board
and connecting the terminals to the proper indicators or actuators (e.g., LEDs, relays,
contactors, etc.).
Note:
The optional ASD
interface
boards
may be used to expand the I/O functionality of the
ASD. See the
P9 ASD Installation and Operation Manual
for more information on
the available options.
Installation Notes
When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at
startup because of insufficient voltage. To avoid this,
DO NOT
connect the brake or the brake contactor
to the output of the ASD.
If an output contactor is used for bypass operation, it must be interlocked such that commercial power is
never applied to the output terminals of the ASD (U/T1, V/T2, and W/T3).
DO NOT
apply commercial power to the ASD output terminals
U/T1
,
V/T2
,
and
W/T3
.
If a secondary magnetic contactor
(MC) is used between the output of the ASD and the motor, it should
be interlocked such that the
ST – CC
connection is disconnected before the output contactor is opened.
DO NOT
open and then close a secondary magnetic contactor between the ASD and the motor unless
the ASD is off and the motor is not rotating.
Note:
Re-application of power via a secondary contact while the ASD is on or while the
motor is still turning may cause ASD damage.
The ASD input voltage should remain within 10% of the specified input voltage range. Input voltages
approaching the upper or lower-limit settings may require that the over-voltage and under-voltage stall
protection level parameters be adjusted. Voltages outside of the permissible tolerance should be
avoided.
The frequency of the input power should be ±2 Hz of the specified input frequency.
DO NOT
use an ASD with a motor that has a current rating that is greater than the rated current of the
ASD.
The P9 ASD is designed to operate NEMA B motors. Consult with your TIC Sales Representative
before using the ASD for special applications such as with an explosion-proof motor or applications
with a piston load.
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.
Interface problems may occur when an ASD is used in conjunction with some types of process
controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (contact
your TIC Sales Representative or the process controller manufacturer for additional information on
compatibility and signal isolation).
