Installing Control Wiring
This chapter describes how to wire the signal and I/O terminal strip
for stop, speed feedback, and remote control signals. Wiring of the
terminal block is detailed in table 7.1.
7.1 Stop Circuit Requirements
Depending upon the requirements of the application, the
SP600 AC drive can be configured to provide either a coast-to-rest
or a ramp-to-rest operational stop without physical separation of the
power source from the motor. A coast-to-rest stop turns off the
transistor power device drivers. A ramp-to-rest stop fires the
transistor power device drivers until the motor comes to a stop, and
then turns off the power devices.
In addition to the operational stop, you must provide a hardwired
emergency stop external to the drive. The emergency stop circuit
must contain only hardwired electromechanical components.
Operation of the emergency stop must not depend on electronic
logic (hardware or software) or on the communication of commands
over an electronic network or link.
Note that the hardwired emergency stop you install can be used at
any time to stop the drive.
!
ATTENTION: You must provide an external, hardwired
emergency stop circuit outside of the drive circuitry. This circuit
must disable the system in case of improper operation.
Uncontrolled machine operation can result if this procedure is
not followed. Failure to observe this precaution could result in
bodily injury.
