Issue:
Program an ATV320 drive to send feedback of motor frequency using the analog output.
Product Line:
Altivar 320
Environment:
All
Cause:
N/A
Resolution:
Go under CONF, FULL, I/O.
AO1 assignment will need to be set motor frequency (OFr).
AO1T for type (current or voltage) (0A=0-20mA,10u=0-10V)
AO1 min for min value such as 0mA or 4mA but can be adjusted to other values.
AO1 max for 10V or 20 mA but can be adjusted.
Scaling of the analog output when set to OFr (motor frequency) is between 0 and tFr (Max Frequency).
tFr is found in the drC- menu (under CONF. / Full-) and will be set to 60 Hz if the bFr parameter is at the factory default of 50Hz. tFr will change to 72 Hz if bFr is changed to 60Hz.
If the customer wants 100% analog output signal to indicate 100% speed (drive is running at High Speed) then tFr may need to be adjusted to match the HSP setting.
