to open immediately so that motor drive is disabled and will not interfere with
the mechanical braking function. In this arrangement, when the brake pedal is
released the controller output accelerates through its programmed acceleration
curve to the existing throttle request.
The controller does not require the pedal signal to engage the main
contactor, and the main contactor will not cycle on and off when the pedal
switch is opened and closed.
EMR REV ENABLE
The emergency reverse enable parameter enables or disables the emergency
reverse function. When it is set to "On," the controller will be prepared to
implement the emergency reverse current limit for enhanced braking and the
direction change to reverse when the emergency reverse input (Pin 7) is pulled
high (to B+). When the emergency reverse enable parameter is set to "Off," the
controller will not respond to any input to Pin 7 and the emergency reverse
current limit and emergency reverse check parameters will not be active.
EMR REV ChECK
The emergency reverse check parameter is applicable only when the emergency
reverse feature is being used in the application. If emergency reverse is not being
used, this parameter should be set to "Off."
When enabled (programmed "On"), the emergency reverse check tests
for continuity from the emergency reverse check output (Pin 22) to the emer-
gency reverse input (Pin 7). Therefore, the emergency reverse wiring should be
connected as closely as possible to the controller side of the emergency reverse
switch, as shown in Figure 13. If the controller detects this open wire fault,
it will disable its output until the wiring fault is fixed. The emergency reverse
function will still be active when this fault exists.
NODE ADDR
The node address parameter determines which address the controller will
respond to when used with a CAN Bus communications system. The address
can be specified from 1 to 15. This parameter is valid only when the CAN Bus
function has been specified for the controller; see Section 4.
