PARAMETER RANGE DESCRIPTION
Partial Decel Rate 0.1 – 30.0 s Sets the rate (in seconds) that is used to slow down the vehicle
Partial_Decel_Rate_SpdM 100 – 30000 when the throttle is reduced without being released to neutral.
0x3082 0x00 Larger values represent slower response.
HS (High Speed) 0 – 100 % Sets the percentage of the Typical Max Speed (page 55) above which
HS 0 – 32767 the “HS” parameters will be used.
0x3076 0x00
LS (Low Speed) 0 – 100 % Sets the percentage of the Typical Max Speed (page 55) below which
LS 0 – 32767 the “LS” parameters will be used.
0x3075 0x00
Reversal Soften 0 – 100 % Larger values create a softer reversal from regen braking to drive
Reversal_Soften 0 – 3000 whennearzerospeed.Thishelpssoftenthetransitionwhentheregen
0x3074 0x00 and drive current limits are set to different values.
Max Speed Accel 0.1 – 30.0 s In some applications, the Max Speed value is changed frequently,
Max_Speed_Accel_SpdM 100 – 30000 through VCL or over the CAN bus. The Max Speed Accel parameter
0x384A 0x00 controls the rate at which the maximum speed setpoint is allowed to
change when the value of Max Speed is raised. The rate set by this
parameter is the time to ramp from 0 rpm to Typical Max Speed rpm.
For example, suppose Max Speed is raised from 1000 rpm to
4000 rpm. If Typical Max Speed is 5000 rpm and the rate is 10.0 seconds,
it will take 10.0 * (4000–1000) / 5000 = 6.0 seconds to ramp from 1000
rpm to 4000 rpm.
Max Speed Decel
0.1 – 30.0 s This parameter works like the Max Speed Accel parameter, except that
Max_Speed_Decel_SpdM 100 – 30000 it controls the rate at which the maximum speed setpoint is allowed to
0x3846 0x00 change when the value of Max Speed is lowered.
For example, suppose you change Max Speed from 4500 rpm
to 2500 rpm. If Typical Max Speed is 5000 rpm, and the rate is 5.0
seconds, it will take 5.0 * (4500–2500) / 5000 = 2.0 seconds to ramp
from 4500 rpm to 2500 rpm.
