Apparatus, system, and method for controlling a handrail of an escalator |
摘要 |
A handrail drive inverter for an escalator can include a memory configured to store instructions, a processor coupled to the memory, an input configured to receive a main speed control signal that corresponds to the speed of a main drive motor of the escalator, and an output configured to provide a handrail speed control signal for a handrail drive motor based on the instructions in the memory. The processor is configured to calculate a torque output of the handrail drive motor and determine the handrail speed control signal as a function of the torque output and a feedback of the handrail speed control signal constrained by at least one of an upper limit and a lower limit, the upper limit and the lower limit being determined from the main speed control signal. |

1. A handrail drive inverter for an escalator, comprising:
a memory configured to store instructions; a processor coupled to the memory and including an input configured to receive a main speed control signal that corresponds to the speed of a main drive motor of the escalator, and an output configured to provide a handrail speed control signal for a handrail drive motor based on the instructions in the memory; wherein the processor is configured to calculate a torque output of the handrail drive motor and determine the handrail speed control signal as a function of the torque output and a feedback of the handrail speed control signal constrained by at least one of an upper limit and a lower limit, the upper limit and the lower limit being determined from the main speed control signal. |
