COMM 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
8
DI1(INV) 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.

20 LIMITS
Defines inverter operation limits.
Note: Speed values are used in vector control and
frequency values are used in scalar control. Select
control mode in 9904 MOTOR CTRL MODE.
2002 MAXIMUM
SPEED
Defines the maximum speed limit. 3000 rpm
0...30000 rpm Maximum speed. 1 = 1 rpm
2003 MAX CURRENT Defines the allowed maximum motor current. I
2N
A
0.0...1.8 I
2N
A Continuous output RMS current. 1 = 0.1 A
2005 OVERVOLT
CTRL
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.

ENABLE Overvoltage control activated 1
