Introduction to 7 ton forklift controller
1. The rated value of the forklift controller is as follows:
1. Controller assembly: power supply voltage DC 48V; maximum current: 25A; operating temperature: -20-60 degrees (-4-140. F); operating voltage range: 28-60V; switching frequency station: about 1.5KHZ.
2. Reactance coil: inductance: 1MH; capacitance: 180∪F/100V; continuous rated current: 8A.
2. The control method is controlled by the voltage signal sent by the steering torque sensor, and a current feedback circuit is installed. EPS motor clockwise/counterclockwise rotation is a control system using FET.
3. Transformation of characteristics. Inversion of the output adjustment switch can change its characteristics. Switch number: 0-5-9; Output: Highest, Lowest; Steering Steering: Steering power for high, heavy, slow steering is the same as for other cases.
4. Disorder detection
1. Electric spike voltage disorder
2. The steering sensor is disconnected and short-circuited, the motor stops - the relay is closed.
3. The motor is short-circuited, the motor stops - the relay is closed.

5. 1. Steering overload protection. When the current is 8 plus or minus and lasts for more than 10 plus or minus 2 seconds, the motor current will gradually decrease. Reset at sensor mid-signal position.

2. Quick back protection after the key switch is turned off. The motor current is gradually reduced after the key switch is turned off.
