(Torque Ramp Down Signal) This function works only if the RAMP STOP SEL (C1) switch is set to
RAMP TO STOP and RAMP DOWN EN SRC (C1) is set to EXTERNAL TB.
up/dwn
(Up/Down Signal) This signal is used to change the sign of the speed command. Default is FALSE;
therefore, positive commands are for the up direction and negative speed command are for the down
direction. Making this input true reverses the car’s direction.
