5000 FLUX
Programming
Speed control, closed loop: rpm
Torque control, speed feedback: Nm
205 Maximum reference
(MAX. REFERENCE)
Value:
Ref
MIN
- 100,000.000
✭
1500.000
Function:
The Maximum reference gives the highest value that
can be obtained by the sum of all references.
Description of choice:
The unit follows the choice of configuration
in parameter 100.
Speed control, closed loop: rpm
Torque control, speed feedback: Nm
206 Ramp type (RAMP TYPE)
Value:
✭
Linear (LINEAR) [0]
Sinusoidal (S1) [1]
Sin
2
(S2)
[2]
Jerk Ctrl
[3]
Function:
There is a choice of 4 different ramp types.
Description of choice:
Select the desired ramp type, depending on
requirements for acceleration/deceleration.
207 Ramp-up time 1
(RAMP UP TIME 1)
Value:
0.00 - 3600 sec. (closed loop)
0.05 - 3600 sec. (open loop)
✭
depends on unit
Function:
The ramp-up time is the acceleration time from
0 rpm to the rated motor speed n
M,N
(parameter
104). This presupposes that the output current does
not reach the torque limit (to be set in parameter
221). Please note, that the value 0.00 corresponds
to 0.01 sec. in speed mode.
Description of choice:
Set the desired ramp-up time.
208 Ramp-down time 1
(RAMP DOWN TIME 1)
Value:
0.00 - 3600 sec. (closed loop)
0.05 - 3600 sec. (open loop)
✭
depends on unit
Function:
The ramp-down time is the deceleration time from
the rated motor speed n
M,N
(parameter 104) to 0
rpm, provided there is no over-voltage in the inverter
because of regenerative operation of the motor, or
if the generated current reaches the torque limit (to
be set in parameter 222). Please note, that the value
0.00 corresponds to 0.01 during speed.
Description of choice:
Set the desired ramp-down time.
