Application Set-Up Examples
1. Make all the parameter changes you need, that is
common for auto and hand mode, like motor
parameters.
2. Set K-10 Active set-up to [9] Multi Set-up. This
parameter change is needed to be able to
change set-up from an external source, like a
digital input.
3. Set K-11 Edit Set-up to [9] Active Set-up. This is
recommended because then the active set-up is
always the set-up that is edited. If you prefer, you
can also ignore this and manually control what
set-up you want to edit through K-11.
4. Set E-03 Terminal 27 Digital Input to [23] Set-up
select bit 0. When terminal 27 is OFF, set-up 1
(hand) is active, when it is ON, set-up 2 (auto) is
active.
5. Set F-01 Frequency Setting 1 to [1] Analog input 53
6 6
(hand mode).
6. Copy set-up 1 to set-up 2. Set K-51 Set up Copy to
[2] Copy to set-up 2. Now set-up 1 and 2 are
identical.
7. If you need to be able to change between hand
and auto mode while the motor is running, you
have to link the 2 set-ups together. Set K-12 This
Set-up Linked to to [2] set-up 2.
8. Change to set-up 2 by setting input 27 ON (if
K-11 is [9]) or by setting K-11 Edit Set-up to set-
up 2.
9. Set F-01 Frequency Setting 1 to [2] Analog input 54
(auto mode). If you want different settings in
hand and auto mode, like different accel/decel
ramps, speed limits you can now program them.
You have to make sure that you edit the correct
set-up. Set-up 1 is Hand mode and set-up 2 is
Auto mode.

6.3 Controls

The frequency converter is capable of controlling either the
speed or the torque on the motor shaft. Setting
parameter H-40 Configuration Mode determines the type of
control.
Speed control
There are 2 types of speed control:
•
Speed open loop control which does not require
any feedback from motor (sensorless).
•
Speed closed loop PID control requires a speed
feedback to an input. A properly optimized speed
closed loop control has higher accuracy than a
speed open loop control.
Selects which input to use as speed PID feedback in
parameter PI-00 Speed PID Feedback Source.
Torque control
The torque control function is used in applications where
the torque on motor output shaft is controlling the
application as tension control. Torque control can be
selected in parameter H-40 Configuration Mode, either in
Advanced Vector Control [4] Torque open loop or Flux
control closed loop with [2] motor speed feedback. Torque
setting is done by setting an analog, digital, or bus
controlled reference. When running torque control, it is
recommended to make a full Auto tune procedure as the
correct motor data are of high importance for optimal
performance.
