Terminal MS Run Application
The elevator controller can calculate the motor present running direction (digital) and objective speed
(digital) according to the elevator control logic and send them to MONT72.
MONT72 receives the objective speed of MS form and calculate the speed curve according to the
S-curve parameter setting, then control the motor to run.
Example:
A certain elevator with rated speed of 1.750m/s uses a controller in terminal MS control
(F00.05 = 2).
The elevator controller controls the running contactor and the MONT72 controls the brake.
•
Inspection running: The elevator controller outputs the multi-speed command.
•
Operating speed: Obtained from the speed combination of the multi-speed terminal.
When the MONT72 receives the enable, direction and multi-speed signal of the elevator controller,
after the F02.01 time at zero speed, the brake is opened, and the MONT72 operates according to the
speed of the elevator controller.
When the machine is stopped, the elevator controller sends a multi-speed zero-speed running
command. After F02.05 time, the brake is released and the elevator stops at zero speed.
Note:
If use gearless permanent magnet syn. motor with SINCOS encoder, MONT72 needs the SINCOS encoder
interface board with FD. MONT72 receive the sine-cosine signal from the encoder as speed signal,
meanwhile MONT72 can output pulse signal of no-FD or 2 - 126 odd-times FD to the elevator controller
without any weigh compensation device.
