Chapter 9 Parameter Descriptions
10 = Jog: An open-to-closed transition on this input while the drive is stopped
causes the drive to start (jog) in the current direction. When the input opens
while the drive is running (jogging), the drive stops.
The drive does not jog while running or while the Stop - Clear Faults input is
open. Start has precedence over jog.
11 and 12 = Jog Forward and Jog Reverse: An open-to-closed transition on one
or both inputs while the drive is stopped causes the drive to jog unless the
Stop - Clear Faults input function is configured and open.
Table 11 describes the
actions taken by the drive in response to various states of these input functions.
Table 11 - Drive Response to Jog Forward and Jog Reverse Inputs
The drive will not jog while running or while the Stop - Clear Faults input is
open. Start has precedence over jog.
If one of these input functions is configured and the other one is not, Table 11
still applies, but consider the unconfigured input function permanently open.
13 = Stop Mode B: This digital input selects between two different drive stop
modes.
If the input is open, then Stop Mode A selects which stop mode to use. If the
input is closed, the Stop Mode B selects which stop mode to use. If this input
function is not configured, then Stop Mode A selects which stop mode to use.
14 = Bus Regulation Mode B: This digital input function selects how the drive
regulates excess voltage on the DC bus.
ATTENTION: If a normal drive start command is received while the drive is
jogging, the drive switches from jog mode to run mode. The drive does not stop,
but may change speed and/or change direction. Failure to observe this
precaution could result in severe bodily injury or loss of life.
Jog
Forward Jog
Reverse Drive Response
Open Open Drive will stop if already jogging, but can be started by other
means.
Open Closed Drive jogs in reverse direction.
Closed Open Drive jogs in forward direction.
Closed Closed Drive continues to jog in current direction.
ATTENTION: If a normal drive start command is received while the drive is
jogging, the drive will switch from jog mode to run mode. The drive will not
stop, but may change speed and/or change direction. Failure to observe this
precaution could result in severe bodily injury or loss of life.
