The GF1-511Electric Forklift Controller is a low-voltage servo motor controller that drives both the traction motor and the hydraulic pump motor of electric forklifts from a single compact unit. Built on sinusoidal FOC closed-loop vector control, it delivers smooth acceleration, precise speed regulation and strong low-speed torque for indoor and outdoor material handling equipment.

Key Features

• Regenerative Braking: Built-in energy feedback returns braking energy to the battery, extending runtime and reducing brake pad wear.
• Dual-Channel Control: Simultaneously drives traction and pump motors with independent parameter sets for optimized forklift performance.
• Servo-Grade Precision: Sinusoidal FOC closed-loop vector control with incremental or Tamagawa absolute encoder feedback ensures smooth, accurate motion.
• Robust Communication: CANopen and RS485 (Modbus) interfaces support fleet management, remote monitoring and PLC integration.
• IP67 Protection: Fully sealed housing resists dust, water spray and harsh warehouse environments.
• Comprehensive Protections: Over-current, over-voltage, under-voltage, over-temperature and motor phase-loss protection for reliable long-term operation.
