ABB ACS880-104

242 Parameters
20.27 Jogging 2 start
source
If enabled by parameter 20.25 Jogging enable, selects the
source for the activation of jogging function 2. (Jogging
function 2 can also be activated through fieldbus regardless
of parameter 20.25.)
1 = Jogging 2 active.
For the selections, see parameter 20.26 Jogging 1 start
source.
Note: If both jogging 1 and 2 are activated, the one that was
activated first has priority.
Not selected
20.30 Enable signals
warning function
Selects enable signal (eg. run enable, start enable) warnings
to be suppressed. This parameter can be used to prevent
these warnings from flooding the event log.
Whenever a bit of this parameter is set to 1, the
corresponding warning is suppressed, ie. no warning is
generated even if the signal is switched off.
The bits of this binary number correspond to the following
warnings:
00b
00b…11b Suppression of “enable signal missing” warnings. 1 = 1
21
21 Start/stop mode
Start and stop modes; emergency stop mode and signal
source selection; DC magnetization settings; autophasing
mode selection.
21.01 Start mode Selects the motor start function for the DTC motor control
mode, ie. when 99.04 Motor control mode is set to DTC.
Notes:
• The start function for the scalar motor control mode is
selected by parameter 21.19 Scalar start mode.
• Starting into a rotating motor is not possible when DC
magnetizing is selected (Fast or Constant time).
• With permanent magnet motors and synchronous
reluctance motors, Automatic start mode must be used.
• This parameter cannot be changed while the drive is
running.
See also section DC magnetization (page 100).
Automatic
Fast The drive pre-magnetizes the motor before start. The pre-
magnetizing time is determined automatically, being typically
200 ms to 2 s depending on motor size. This mode should be
selected if a high break-away torque is required.
