6.1.2 Parameter x.00 reset
When an action is started by setting Pr x.00 to one of the above values
and initiating a drive reset this parameter is cleared when the action is
completed successfully. If the action is not started, e.g. because the
drive is enabled and an attempt is made to load defaults, etc., Pr x.00 is
not cleared and no trip is produced. If the action is started and then fails
for some reason a trip is always produced and Pr x.00 is not cleared. It
should be noted that parameter saves etc. can also be initiated with the
copying parameter (Pr 11.42 (SE09, 0.30)). If actions that can be
initiated by either parameter are started and then completed successfully
Pr x.00 is cleared and Pr 11.42 (SE09, 0.30) is cleared if it has a value of
less than 3.
It should be noted that there could be some conflict between the actions
of Pr x.00 and Pr 11.42 (SE09, 0.30) Parameter copying when the drive
is reset. If Pr 11.42 (SE09, 0.30) has a value of 1 or 2 and a valid action
is required from the value of Pr x.00 then only the action required by
Pr x.00 is performed. Pr x.00 and Pr 11.42 (SE09, 0.30) are then reset to
zero. If Pr 11.42 (SE09, 0.30) has a value of 3 or 4 it will operate
correctly causing parameters to be save to a SMARTCARD each time a
parameter save is performed.
6.1.3 Set-up
SE01
Minimum reference clamp
{0.22, 1.07}
RW Bi
±SPEED_LIMIT_MAX rpm
(When the drive is jogging, this parameter has no effect.)
Set SE01 (Pr 0.22, 1.07) at the required minimum motor speed for both
directions of rotation. The drive speed reference is scaled between SE01
(Pr 0.22, 1.07) and SE02 (Pr 0.23, 1.06).
SE02
Maximum reference clamp
{0.23, 1.06}
RW Bi
SPEED_LIMIT_MAX rpm
(The drive has additional over-speed protection.)
Set SE02 (Pr 0.23, 1.06) at the required maximum motor speed for both
directions of rotation. The drive speed reference is scaled between SE01
(Pr 0.22, 1.07) and SE02 (Pr 0.23, 1.06).
SE03
Acceleration rate
{0.24, 2.11}
RW Uni
0 to MAX_RAMP_RATE
s/(SE02 [Pr 0.23, 1.06] or
Pr 2.39)
Set SE03 (Pr 0.03, 2.11) at the required rate of acceleration.
Note that larger values produce lower acceleration. The rate applies in
both directions of rotation.
SE04
Deceleration rate
{0.25, 2.21}
RW Uni
0 to MAX_RAMP_RATE
s/(SE02 [Pr 0.23, 1.06] or
Pr 2.39)
Set Pr SE04 (Pr 0.25, 2.21) at the required rate of deceleration.
Note that larger values produce lower deceleration. The rate applies in
both directions of rotation.

*Pr 1.41 to Pr 1.44 and Pr 1.52 can be controlled by digital inputs to force
the value of Pr 1.49:
When all bits = 0, Pr 1.49 =1
Pr 1.41 = 1 then Pr 1.49 = 2
Pr 1.42 = 1 then Pr 1.49 = 3
Pr 1.43 = 1 then Pr 1.49 = 4
Pr 1.44 = 1 then Pr 1.49 = 5
Pr 1.52 = 1 then Pr 1.49 = 6
The bit parameters with lower numbers have priority over those with
higher numbers.
Pr 1.49 and Pr 1.50 then define the reference as follows:
Pr 1.49 Pr 1.50
1 1
1 >1
2 1
2 >1

Keypad reference
If Keypad reference is selected the drive sequencer is controlled directly
by the keypad keys and the keypad reference parameter (Pr 1.17) is
selected. The sequencing bits, Pr 6.30 to Pr 6.34, have no effect and jog
is disabled.
