Elevator Core Reference Guide

1

STO Input (STO1 & STO2) Closed by External control system.

2

Direction (DI1 or DI2) and Speed reference Inputs (DI4 for high speed as default) given by External Control System.

3

Relay 1 closes and thus closes motor contactor (if motor contactor controlled by Drive).

4

If not using Motor contactor feedback signal then drive waits for Motor Contactor Closing time (P3-01).

4

If Motor contactor feedback signal is being used (see section 15.7.2) then drive waits until this has been received, (if not received within the period of Output Contactor Closing time P3-01 or if feedback signal is received before Step 3 then drive will trip on motor contactor error (CF-Err)

5

Drive Output Stage turns-on

6

Drive performs motor connected check (P10-08)

7

Magnetisation time starts and gives current to the motor

8

DC injection current at start (P9-12) and motor bake release time (P5-01) starts

And Drive releases brake via relay 2

9

DC injection continues for time set in DC injection time at start (P9-11)

10

When DC injection time at start has ended or Brake release time has ended (whichever is the longest) Drive accelerates up to commanded speed reference.

11

When High speed input (default DI4) is removed, and levelling speed input is given (default is DI3) the drive decelerates down to levelling speed (P8-05)

12

When direction command (DI1/DI2) is removed the drive decelerates down to 0 speed. (P5-03 value ?)

13

When the motor reaches zero speed/value set in DC injection speed on stop (P9-15) :

and

14

When Zero speed holding time on disable (P9-22) has ended Relay 2 will open to apply the Electromechanical brake.

15

After the time set in brake apply delay (P5-02) or DC Injection time at stop (P9-13) has ended (whichever is the longest) torque drop off will be performed.(P4-17)

16

Motor Contactor relay (Relay 1 on the drive as default) will open motor contactor and drive output will turn off.
