KSI SRO ENABLE
The keyswitch static return to off (SRO) feature prevents the vehicle from be-
ing started when “in gear.” When this parameter is enabled, the controller must
initially sense the KSI input in the Off position (upon vehicle power-up) prior
to it being switched to the On position. This feature is used to prevent vehicle
motion due to a KSI short circuit or due to the keyswitch being permanently
locked in the On position.
MODE AFTER KEY
The mode change after keyswitch parameter determines whether the operat-
ing mode (M1, M2) can be changed after KSI has been activated. If
MODE AFTER
KEY is enabled, the mode can be changed while the vehicle is being operated.
The settings are gradually slewed between the two modes so as to reduce the
abruptness of the transition. However, if the settings for Mode 1 greatly differ
from those of Mode 2, switching from one mode to the other while driving
may cause the vehicle performance to change drastically.
If MODE AFTER KEY is not enabled, the mode can be changed only when
keyswitch is off.
OVERVOLTAGE
The overvoltage parameter sets the overvoltage protection threshold for the
electronic system. This parameter determines when regen should be cut back
to prevent damage to batteries and other electrical system components due to
overvoltage.
A non-adjustable internal threshold also exists, to prevent damage within
the controller.
LOW VOLTAGE
The low voltage parameter sets the undervoltage threshold to protect the system
from operating at voltages lower than its electronics were designed for. At this
threshold voltage, the drive current will taper off until it reaches the controller’s
internal threshold for safe operation. This will ensure proper operation of all
electronics whenever the vehicle is driven.
