25 START (START MODE)
Automatic start of equipment may result in damage to equipment and/or injury to personnel!
Automatic start should only be used on equipment that is inaccessible to personnel.
This parameter selects the starting method for the drive, and can be set for one of the following:
NORMAL The drive will start when the appropriate contact closure is made (maintained or
momentary depending on whether the drive is set up for a two-wire or three-wire
start/stop) on the terminal strip. To start the drive in NORMAL mode, a start
command must be issued at least two seconds AFTER input power is applied.
POWER-UP The drive will automatically start upon application of input power. The drive MUST
be wired for a two-wire start/stop control with a maintained start contact (refer to
Section 14.0 - CONTROL WIRING). The start command MUST be present when
power is applied for this function to operate.
AUTO RE- The drive will automatically restart after a protective fault or upon application of input
power. As with the POWER-UP option, a start command must be present for this
function to operate.
RE-BRAKE After a fault, the drive will apply voltage equal to the DC BRAKE setting for 15
seconds and then restart. This is done to ensure the motor is topped at the time of the
restart attempt as the drive will not start into a spinning motor.
NOTE 1: POWER UP, AUTO RE-, and RE-BRAKE settings are only active when the drive is in REMOTE
mode (see Parameter 30 - CONTROL).
NOTE 2: After a fault, the drive will attempt to restart five times, and if unsuccessful, will shut down on a
FAULT LOCKOUT. Every 15 minutes that passes will decrement the restart counter by one. Therefore, 75
minutes after a successful restart, the restart counter is fully reset, and the drive can once again attempt five
restarts.
NOTE 3: The drive WILL NOT restart after the following faults: CONTROL and PWR SAG. Also, if
an output fault occurs at a speed below 1.5 Hz, only one restart will be attempted because there may be a
problem with an output transistor. If unsuccessful, it will then trip into FAULT LOCKOUT, which will
require a manual reset. This is done to protect the drive in case of a shorted motor.
26 STOP (STOP MODE)
This parameter selects whether the motor will COAST to a stop, or RAMP to a stop, when the drive is given
a stop command.
COAST When a stop command is given, the drive shuts off the output to the motor, allowing
it to coast to a stop. In this mode, the time it takes the motor to stop is governed by the
inertia of the driven load.
RAMP When a stop command is given, the drive will decelerate the motor to a stop over a
period of time according to Parameter 8 - DECEL.
