204 Minimum reference
(MIN. REFERENCE)
Value:
-100,000.000 - Ref (PAR. 205)
MAX
0.000
Depends on parameter 100.
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)
Value:
Ref (parameter 204)-100,000,000
MIN
50.000 HZ
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.
207 Ramp-up time 1
(RAMP UP TIME 1)
Value:
0.15 - 3600.00 sec.
3.00 sec.
Function:
The ramp-up time is the acceleration time from 0
Hz to the rated motor frequency f
104). This presupposes that the current limit is not
reached (to be set in parameter 221).

208 Ramp-down time 1
(RAMP DOWN TIME 1)
Value:
0.15 - 3600.00 sec.
3.00 sec.
Function:
The ramp-down time is the deceleration time from
the rated motor frequency f
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.
209 Ramp-up time 2
(RAMP UP TIME 2)
Value:
0.15 - 3600.00 sec.
3.00 sec.
Function:
The ramp-up time is the acceleration time from 0
Hz to the rated motor frequency f
104). This presupposes that the current limit is not
reached (to be set in parameter 221).
Description of choice:
Program the desired ramp-up time.
Shift from ramp 1 to ramp 2 by activating
ramp 2 via a digital input.
