VACON® NX All-in-One
Application Guide
• P2.3.18 (Local/Remote Control Application, Multi-Step Speed Control Application, PID Control Application)
• P2.3.4.9 (Multi-Purpose Control Application)
• P2.3.2.9 (Pump and Fan Control Application)
Use this parameter to set the delay time to open the brake after the conditions to open the brake are filled.
See 10.111 (ID 353) External Brake-On
10.111 (ID 353) External Brake-On Delay
Location in the menu:
• P2.3.19 (Local/Remote Control Application, Multi-Step Speed Control Application, PID Control Application)
• P2.3.4.10 (Multi-Purpose Control Application)
• P2.3.2.10 (Pump and Fan Control Application)
Use this parameter to set the delay time to close the brake after the conditions to close the brake are filled.
The function of the external brake can be timed to the start and stop control signals with these parameters. See
10.620 External Brake Control with Additional Limits (IDs 315, 316, 346–349, 352,
The brake control signal can be programmed via the digital output DO1 or via one of the relay outputs RO1 and RO2. See parame-
ters ID 312 to ID 314 (Local/Remote Control Application, Multi-Step Speed Control Application, PID Control Application) or ID 445
(Multi-Purpose Control Application, Pump, and Fan Control Application). The brake-on delay is ignored when the unit is reaching a
stop state after a ramp-down or if stopped by coasting.

P2.3.2.11 (Pump and Fan Control Application)
Use this parameter to select the limit supervision function for the temperature of the AC drive.
If the temperature of the AC drive unit falls below or exceeds the set limit (ID 355), this function generates a message through a
digital output depending on:
•
the settings of parameters ID 312 to ID 314 (Local/Remote Control Application, Multi-Step Speed Control Application, PID Con-
trol Application), or
•
to which output the temperature limit supervision signal (parameter ID 450) is connected (Multi-Purpose Control Application,
Pump and Fan Control Application).
