6.3.3 Status information
The parameter displays the software version of the drive
6.3.4 Speed limits
Open-loop
Set Pr 00.010 at the required minimum output frequency of the drive for
both directions of rotation. The drive speed reference is scaled between
Pr 00.010 and Pr 00.011. [00.010] is a nominal value; slip compensation
may cause the actual frequency to be higher.
RFC-A / RFC-S
Set Pr 00.010 at the required minimum motor speed for both directions
of rotation. The drive speed reference is scaled between Pr 00.010 and
Pr 00.011.
(The drive has additional over-speed protection).
Open-loop
Set Pr 00.011 at the required maximum output frequency for both
directions of rotation. The drive speed reference is scaled between
Pr 00.010 and Pr 00.010. [00.011] is a nominal value; slip compensation
may cause the actual frequency to be higher.
RFC-A / RFC-S
Set Pr 00.011 at the required maximum motor speed for both directions
of rotation. The drive speed reference is scaled between Pr 00.010 and
Pr 00.011.
For operating at high speeds see section 8.4 High speed operation on
page 162.
6.3.5 Ramps
Set Pr 00.012 to the required rate of acceleration.
Note that larger values produce lower acceleration. The rate applies in
both directions of rotation.
Set Pr 00.013 to the required rate of deceleration.
Note that larger values produce lower deceleration. The rate applies in
both directions of rotation.
6.3.6 Voltage boost, (open-loop), Speed-loop PID
gains (RFC-A / RFC-S)
Open-loop
There are seven voltage modes available, which fall into three
categories, vector control, fixed boost and single phase current output.
For further details, refer to section 8.1.1 Open loop motor control on
page 151.
RFC-A/ RFC-S
Pr 00.014 (03.010) operates in the feed-forward path of the speed-
control loop in the drive. See Figure 11-4 Menu 3 RFC-A, RFC-S logic
diagram on page 214 for a schematic of the speed controller. For
information on setting up the speed controller gains, refer to section
8 Optimization on page 151.
Open-loop
Set Pr 00.015 (05.013) at 0 when the V/f characteristic applied to the
motor is to be fixed. It is then based on the rated voltage and frequency
of the motor.
Set Pr 00.015 at 1 when reduced power dissipation is required in the
motor when it is lightly loaded. The V/f characteristic is then variable
resulting in the motor voltage being proportionally reduced for lower
motor currents. Figure shows the change in V/f slope when the motor
current is reduced.
