204 Minimum reference
(MIN. REFERENCE)
Settings:

[0]
Function:
The
Minimum reference
gives the minimum setting
that can be assumed by the sum of all references.
Minimum reference
is only active if
Min - Max
[0] has
been set in parameter 203; however, it is always
active in
Process, closed loop mode
(parameter
100).
Description of choice:
Is only active when parameter 203 has been set to
Min - Max
[0].
Set the desired value.
205 Maximum reference
(MAX. REFERENCE)
Settings:
Ref

Function:
The
Maximum reference
gives the highest value that
can be assumed by the sum of all references.
If parameter 100 has been selected to open loop
the max. setting is 132 Hz.
If closed loop has been selected the maximum
reference cannot be set higher than the maximum
feedback (parameter 415).
Description of choice:
Set the desired value.

✭
3.00 sec.
[300]
Function:
The ramp-up time is the acceleration time from 0 Hz
to the rated motor frequency f
M,N
(parameter 104).
This assumes that the current limit is not reached
(to be set in parameter 221).
Description of choice:
Program the desired ramp-up time.
208 Ramp-down time (RAMP DOWN TIME )
Settings:

[5 - 360000]
H

✭
3.00 sec.
[300]
Function:
The ramp-down time is the deceleration time from
the rated motor frequency f
M,N
(parameter 104) to 0
Hz provided there is no over-voltage in the inverter
because of regenerative operation of the motor, and
the current limit is not reached (to be set in
parameter 221).
Description of choice:
Program the desired ramp-down time.
10-3
Description of choice:
Choose the desired range.
