CHAPTER 6
Installing Regulator Board Control
Wiring
This chapter describes how to wire the signal and I/O terminal strip for stop, speed
feedback, and remote control signals.
6.1 Stop Circuit Requirements
Depending upon the requirements of the application, the GV6000 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 stop external to the
drive. This stop circuit must contain only hardwired electromechanical components.
Operation of the hardwired 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 stop you install can be used at any time to stop the drive.
6.1.1 User-Initiated Stopping
The terminal block Drive Enable input and the Function Loss input, if configured, are
always active. This is independent of the Logic Source Select setting. The terminal
block Stop input must be closed only when the terminal block is selected as the logic
source. Refer to figure 6.1.
!
ATTENTION: The user must provide an external, hardwired stop circuit
outside of the drive circuitry. This circuit must disable the system in case
of improper operation. Uncontrolled machine operation may result if this
procedure is not followed. Failure to observe this precaution could result
in bodily injury.
!
ATTENTION: Note the following about stop commands:
• A stop command from any attached OIM will always be enabled
regardless of the value of Logic Source Sel.
• Network stop commands are effective only when Logic Source Sel is
set to Network or All Ports.
• Terminal block stop commands are effective only when Logic Source
Sel (89) is set to Terminal Blk or All Ports.
Failure to observe these precautions could result in severe bodily
injury or loss of life.
