Group 3.2: Start/Stop setup

Start/Stop commands are given differently depending on the control place.
Auto control place (I/O A): Start, stop and reverse commands are controlled by 2 digital inputs chosen
with parameters P3.5.1.1 and P3.5.1.2. The functionality/logic for these inputs is then selected with pa-
rameter P3.2.6 (in this group).

Default ID
0 = Not used
1 = Always in stop state
2 = Controlled by DI
0 1225 3 = Temp limit (heat sink)
NOTE: Virtual digital input
can be activated by Real
Time Clock
Motor preheat is switched
on when the heat sink tem-
perature goes below this
level (if par. P3.1.2.5 is set
to Temperature limit.
0 1226
If limit is e.g. 10 °C (50 °F)
feeding current starts at 10
°C and stops at 11 °C
(51.8°)
(1 °C (1.8 °F) hysteresis).
DC current for pre-heating
of motor and drive in stop
Varies 1227 state. Activated by digital
input or by temperature
limit.
Type of U/f curve between
zero frequency and the field
Varies 108 weakening point.

Parameter for adjusting sta-
100.0 659 tor voltage in permanent
magnet motors.
The drive searches for the
minimum motor current in
order to save energy and to
lower the motor noise. This
0 666 function can be used for
example in fan and pump
applications
0 = Disabled
1 = Enabled
0 = Shaft direction is
searched in both
directions.
0 1590 1 = Shaft direction is only
searched in the same
direction as the frequency
reference
