ABB ACQ810, Firmware Manual

Page: 171 / 376

Parameters 171
20.03 Pos speed ena Selects the source of the positive speed reference enable
command.
1 = Positive speed reference is enabled.
0 = Positive speed reference is interpreted as zero speed
reference (In the figure below
03.03 SpeedRef unramp is set
to zero after the positive speed enable signal has cleared).
The speed reference is set to zero and the motor is stopped
along the currently active deceleration ramp.
Example: The motor is rotating in the forward direction. To
stop the motor, the positive speed enable signal is
deactivated by a hardware limit switch (e.g. via a digital
input). If the positive speed enable signal remains
deactivated and the negative speed enable signal is active,
only reverse rotation of the motor is allowed.
Const Bit pointer setting (see Terms and abbreviations on page
109 ).

20.04 Neg speed ena Selects the source of the negative speed reference enable
command. See parameter
20.03 Pos speed ena .
Const Bit pointer setting (see Terms and abbreviations on page
109 ).

Pointer
20.05 Maximum current Defines the maximum allowed motor current.
0.00 … 30000.00 A Maximum motor current. 100 = 1 A
20.06 Torq lim sel Defines a source that selects between the two sets of torque
limits defined by parameters
20.07 … 20.10 .
0 = The torque limits defined by parameters 20.07 Maximum
torque1 and 20.08 Minimum torque1 are in force.
1 = The torque limits defined by parameters 20.09 Maximum
torque2 and 20.10 Minimum torque2 are in force.
Const Bit pointer setting (see Terms and abbreviations on page
109 ).

Pointer
20.07 Maximum torque1 Defines maximum torque limit 1 for the drive (in percent of
the motor nominal torque). See parameter
20.06 Torq lim
sel .
0.0 … 1600.0% Maximum torque 1. 10 = 1%
20.08 Minimum torque1 Defines minimum torque limit 1 for the drive (in percent of
the motor nominal torque). See parameter
