10.473 (ID 1267) Brake Chopper Level
Location in the menu:
P2.4.24
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the brake chopper level.
This parameter defines brake chopper control activation level in voltage. This parameter is active when ID 1262 Overvoltage refer-
ence selection is 2 = Brake Chopper Level.
For 400 V supply: 400*1.35*1.18 = 638 V DC
For 500 V supply: 500*1.35*1.18 = 797 V DC
For 690 V supply: 690*1.35*1.18 = 1100 V DC
