RANGE
0–3 Configures mode switch operation.
0 = Standard M1/M2 MultiMode operation.
When the mode switch is open, the programmed M1 parameter
settings for Accel Rate, Decel Rate, Brake Rate, Min Speed, and Max
Speed are in effect; when the mode switch is closed, the programmed M2
parameter settings are in effect.
1 = Creep
Same as 0, except when the vehicle is operating in Mode 2, the
interlock switch input is ignored.
2 = Coast
Same as 0, except when the vehicle is operating in Mode 1, the
Coast Deceleration Rate is in effect when the throttle is reduced or re-
leased. (When the opposite direction is selected, the M1 Brake Rate is in
effect.)
3 = Secure Creep
Same as 0, except that the transition from Mode 2 to Mode 1 is only
possible when interlock is Off or throttle input is 0.
Defines how quickly the controller reduces its output to zero when the
throttle is released. This parameter allows adjustment for different sized
vehicles. Lower values represent faster deceleration and thus a shorter
coasting distance. The Coast Decel Rate only applies when the Mode
Select Type is set to Type 2 and the vehicle is operating in Mode 1.
/ The anti-tiedown feature prevents operators from taping or "tying down"
OFF ON
the mode switch in order to operate permanently in Mode 2, which is
typically the high speed mode. Upon startup, when the interlock switch is
first closed, the controller will ignore the request and default to Mode 1.
The controller will remain in Mode 1 until the mode switch is released and
reactivated.
For safety, anti-tiedown should be used only when Mode 2 is faster
than Mode 1.
