Table 4-10 Parameter setting for bypass function with synchronization with overlap
Parameter Description
p1262 = Bypass dead time setting
p1263 = Debypass dead time setting
p1264 = Bypass delay time setting
p1265 = Speed threshold setting when p1267.1 = 1
p1266 = Control signal setting when p1267.0 = 1
p1267.0 =
p1267.1 =
p1267.2 =
Trigger signal setting for bypass function
P1269[0] = Signal source to provide the feedback signal of contactor K1
P1269[1] = Signal source for contactor K2 feedback
p3800 = 1 The internal voltages are used for synchronization.
p3802 = r1261.2 Synchronizer activation is triggered by the bypass function.
