Use this parameter to select a digital output for the reverse status.
TTF programming method must be applied to this parameter (see
10.626 "Terminal to Function" (TTF) Programming Principle ).
10.185 (ID 441) Unrequested Direction
Location in the menu:
P2.3.1.10 (Pump and Fan Control Application)
P2.3.3.10 (Multi-Purpose Control Application)
Use this parameter to select a digital output for the direction difference status.
TTF programming method must be applied to this parameter (see
10.626 "Terminal to Function" (TTF) Programming Principle ).
Motor rotation direction is different from the requested one.
10.186 (ID 442) At Speed
Location in the menu:
P2.3.1.11
(Pump and Fan Control Application)
P2.3.3.11 (Multi-Purpose Control Application)
Use this parameter to select a digital output for the motor running at reference speed status.
The output frequency has reached the set reference.
Hysteresis is equal to motor nominal slip with induction motors and to 1.00 Hz with PMS motors.
10.187 (ID 443) Jogging Speed
Location in the menu:
P2.3.1.12 (Pump and Fan Control Application)
P2.3.3.12
(Multi-Purpose Control Application)
Use this parameter to select a digital output for the jogging speed status.
TTF programming method must be applied to this parameter (see
10.626 "Terminal to Function" (TTF) Programming Principle ).
10.188 (ID 444) I/O Control Place Active
Location in the menu:
P2.3.1.13 (Pump and Fan Control Application)
P2.3.3.13 (Multi-Purpose Control Application)
Use this parameter to select a digital output for the external control place status.
TTF programming method must be applied to this parameter (see
10.626 "Terminal to Function" (TTF) Programming Principle ).
10.189 (ID 445) External Brake Control
Location in the menu:
P2.3.1.14
(Pump and Fan Control Application)
P2.3.3.14 (Multi-Purpose Control Application)
Use this parameter to select a digital output for the external brake control status.
TTF programming method must be applied to this parameter (see
10.626 "Terminal to Function" (TTF) Programming Principle ).
See 10.620 External Brake Control with Additional Limits (IDs 315, 316, 346–349, 352, 353) for details.
Example: RO1 on OPTA2 board:
Brake function ON: Terminals 22–23 are closed (relay is energized).
Brake function OFF: Terminals 22–23 are open (relay not energized).
When power from control board is removed, the terminals 22–23 open.
When using the Master Follower function, the follower drive opens the brake at the same time as the Master does even if the Fol-
lower's conditions for brake opening have not been met.
