Installation And Connections; Installation Notes - Toshiba ACE-tronics G9 ASD Installation And Operation Manual

Installation and Connections

The ACE-tronics G9 ASD 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 ACE G9-120V-PCB 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
ACE G9-120V-PCB and connecting the terminals to the proper indicators or actuators (LEDs, relays,
contactors, etc.).
Note: The optional ACE-tronics G9 ASD interface boards may be used to expand the I/O
functionality of the ASD.

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.
Though the default settings of the ASD do not include the use of a physical discrete input terminal being
programmed to the ST function, the system may be configured to use a physical discrete input terminal
set to ST. When configured properly, the externally-activated ST terminal acts as a permissive in
allowing for normal system operation. See parameter
terminal.
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 terminal activation is deactivated 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 power rating higher than the rated output of the ASD.
The ACE-tronics G9 ASD is designed to operate NEMA B motors. Consult with the ACE World
Companies Customer Support Center 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.
