MP_ampVoltProtection
Field weakening for synchronous motors
Available from NCK software version: 597 110-05.
Format: Selection menu
Selection: not installed – mode 1
(cf. iTNC 530: MP2160.x = 0)
Mode 1: There is no voltage-protection module (SM). No field 
weakening possible.
installed – mode 2
(cf. iTNC 530: MP2160.x = 1)
Mode 2: Voltage-protection module (SM) exists. Field 
weakening without speed limitation is possible. Use this mode 
for synchronous spindles and torque motors, for example.
not installed – mode 3
(cf. iTNC 530: MP2160.x = 2)
Mode 3: There is no voltage-protection module (SM). Field 
weakening with speed limitation is possible. Use this mode for 
EcoDyn motors, for example.
installed – mode 4
(cf. iTNC 530: MP2160.x = 9)
Mode 4: Like mode 2, but with minimized total current.
not installed – mode 5
(cf. iTNC 530: MP2160.x = 10)
Mode 5: Like mode 3 but with minimized total current.
Default: Not installed
Access: LEVEL3
