7.2.3 Programming Example for an Open-loop Application
This procedure, which is used to configure a typical open-loop application, programs the drive to receive a 0–10 V DC analog control
signal on input terminal 53. The drive responds by providing 20–50 Hz output to the motor proportional to the input signal (0–10 V
DC=20–50 Hz). The wiring connections used to enable the external device set-up are shown in
.
Procedure
Press [Quick Menu].
Select Q3 Function Setups and press [OK].
Select Parameter Data Set and press [OK].
Select Q3-2 Open Loop Settings and press [OK].
Select Q3-21 Analog Reference and press [OK].
Select
parameter 3-02 Minimum Reference
. Set the minimum internal drive reference to 0 Hz and press [OK].
Select
parameter 3-03 Maximum Reference
. Set the maximum internal drive reference to 60 Hz and press [OK].
Select
parameter 6-10 Terminal 53 Low Voltage
. Set the minimum external voltage reference on terminal 53 at 0 V and press
[OK].
Select
parameter 6-11 Terminal 53 High Voltage
. Set maximum external voltage reference on terminal 53 at 10 V and press
[OK].
Select
parameter 6-14 Terminal 53 Low Ref./Feedb. Value
. Set minimum speed reference on terminal 53 at 20 Hz and press
[OK].
Select
parameter 6-15 Terminal 53 High Ref./Feedb. Value
. Set maximum speed reference on terminal 53 at 50 Hz and press
[OK].
With an external device providing a 0–10 V control signal connected to drive terminal 53, the system is now ready
for operation.
