Method 2: Direct docking terminal function (using multi-step speed change)
The steps to execute direct docking terminal function using deactivating multi-step speed command 1 and
2 (MI1 and MI2) are as follows:
1. The control mode should be in closed-loop. Set Pr.00-09 = 3 (FOCPG) or 8 (FOCPM).
2. Set Pr.00-14 = 3 (External digital input).
3. Set Pr.00-15 = 1 (External terminals).
4. Set Pr.04-00 = 0 (Zero-step speed frequency must be set to 0 Hz).
5. Set Pr.04-01 (First-step Speed Frequency).
6. Set Pr.04-03 (Third-step Speed Frequency).
7. Increase Pr.01-13 appropriately in case the elevator stops while having not reached the leveling plate.
8. Set Pr.01-35 (Limit for Direct Docking Terminal Function). In normal condition, there is no need to
adjust this parameter.
9. Set Pr.01-36 (Deceleration Distance for Direct Docking Terminal Function). Enter the length of leveling
plate.
10. Set Pr.01-38 = 2 (Direct docking terminal function enabled).
11. Set Pr.11-01 (Elevator speed). Deceleration speed for terminal function direct docking is calculated
according to this parameter.
NOTE: Do NOT set multi-function (MI) terminal to 53.
RUN command
Elevator runs in high speed:
the third-step speed
command is given (MI1 and
MI2 enabled)
During deceleration, when
the host controller receives
signals of LU, LD or docking,
it sends an zero-step speed
(MI1 disabled) command
to
VFD-ED.
Elevator runs in low speed:
the first-step speed
command is given (MI1
enabled and MI2 disabled)
Elevator starts
Elevator stops
Executes direct docking
according to Pr.01-36
deceleration distance
