Description
Fieldbus interface as the source for the local lock, that
is Control word 0301 FB CMD WORD 1 bit 14 (see
ACS355 User's manual (3AUA0000066143
[English])). The Control word is sent by the fieldbus
controller through the fieldbus adapter or embedded
fieldbus (Modbus) to the drive. For the Control word
bits, see section DCU communication profile in
ACS355 User's manual (3AUA0000066143 [English]).
Note: This setting applies only for the DCU profile
Local lock through inverted digital input DI1.
Raising edge of inverted digital input DI1: Local control
allowed.
Falling edge of inverted digital input DI1: Local control
disabled.

Defines the maximum speed limit.
Maximum speed.
Defines the allowed maximum motor current.
Continuous output RMS current.
Activates or deactivates the overvoltage control of the
intermediate DC link.
Fast braking of a high inertia load causes the voltage
to rise to the overvoltage control limit. To prevent the
DC voltage from exceeding the limit, the overvoltage
controller automatically decreases the braking torque.
Note: If a brake chopper and resistor are connected to
the drive, the controller must be switched off (selection
DISABLE) to allow chopper operation.
Overvoltage control deactivated
