Siemens

Using a Siemens motor inverter with an Lithiumate BMS.

Function	BMS	Motor driver	Connection	BMS configuration	Notes
Drive disable	LLIM /pin 10	Emergency off / Notaus / Pin 2	Direct	Set normally open, Limit grounded (default)	REQUIRED
Regen disable	HLIM /pin 11	Brake pedal wiper / Schleifer Bremsgeber / Pin 17	Place 1 kOhm resistor between pot wiper and pin 17 of motor driver; wire BMS directy to motor driver.	Set normally open, Limit grounded (default)	REQUIRED
End of charge step reduction	FLT /pin 12	Power reduction / Leistungsreduzierung / Pin 20	Direct	Set FLT out as a Warning out. Set normally open, warning grounded (default)	Optional
End of charge gradual reduction	DCL /pin 14	Accelerator pedal wiper / Schleifer Fahrgeber / Pin 34	Place 1 kOhm resistor between pot wiper and pin 34 of motor driver. Place diode, between BMS and motor driver, anode to motor driver.	Set 5 V OK down to 0 V disable (default)	Optional
