11§Scope: maximum speed of 4m / s, the highest floor of 50-story elevator drive case.
The main function:
1§High-performance precise distance control mode: direct dock, choose the most high-speed efficiency, leveling quasi-intelligent hoistway self-learning function。
2§Auto memory the number of pulses on each floor, automatically calculates the division factor monitoring dedicated debugging software: WINDOWS interface with analog oscilloscope and logic analyzer, comfortable, more flexible S-curve calculation function。
3§With a jerk, and deceleration setting maximum deceleration setting torque bias function, according to the input signal weighing, automatic control starting torque to ensure a smooth start elevator safety。
4§Forced deceleration control to prevent the car jump and squatting bottom, emergency power operating mode when the input power source fails, rely on the battery control stops nearby elevator floor, perfect for the protection and chain elevator overspeed protection function, the leveling signal failure, the brake contactor failure, malfunction forced deceleration switch operation, operating logic failure, and brake contactor interlock control function。
5§Enhancement and maintenance functions, running times and memory function, maintenance and trouble to run when the number of automatic dialing, analog and digital I / O check function, and the current floor position display function, easy elevator maintenance, and repair Run。
6§Standard GB4943-1995, GB7588-1995, EN12015, EN12016: 1998 and other low-cost built PG cards can provide 24V / 15V / 12V / 8V / multi-voltage 5V power supply; 22KW following built-in brake unit, the system into a rich programmable input and output terminals: allows any user control system interface, reducing additional configuration。
