FREQUENCY REFERENCE
It is possible to program the source of the frequency reference in all the control places,
except the PC tool. If you use your PC, it always takes the frequency reference from the PC
tool.
REMOTE CONTROL PLACE (I/O A)
To set the source of the frequency reference for I/O A, use the parameter P3.3.1.5 .
REMOTE CONTROL PLACE (I/O B)
To set the source of the frequency reference for I/O B, use the parameter P3.3.1.6.
LOCAL CONTROL PLACE (KEYPAD)
If you use the default value keypad for the parameter P3.3.1.7, the reference that you set for
P3.3.1.8 Keypad Reference applies.
REMOTE CONTROL PLACE (FIELDBUS)
If you keep the default value fieldbus for the parameter P3.3.1.10, the frequency reference
comes from fieldbus.
P3.3.1.1 MINIMUM FREQUENCY REFERENCE (ID 101)
Use this parameter to set the minimum frequency reference.
P3.3.1.2 MAXIMUM FREQUENCY REFERENCE (ID 102)
Use this parameter to set the maximum frequency reference.
P3.3.1.3 POSITIVE FREQUENCY REFERENCE LIMIT (ID 1285)
Use this parameter to set the final frequency reference limit for the positive direction.
P3.3.1.4 NEGATIVE FREQUENCY REFERENCE LIMIT (ID 1286)
Use this parameter to set the final frequency reference limit for the negative direction.
Use this parameter for example to prevent the motor from running in the reverse direction.
P3.3.1.5 I/O CONTROL REFERENCE A SELECTION (ID 117)
Use this parameter to select the reference source when the control place is I/O A.
The application that you set with parameter 1.2 gives the default value.
P3.3.1.6 I/O CONTROL REFERENCE B SELECTION (ID 131)
Use this parameter to select the reference source when the control place is I/O B.
See P3.3.1.5 for more information. You can force the I/O B control place to be active only with
a digital input (P3.5.1.7).
