A141 [Purge Frequency]
Related Parameter(s):
Provides a fixed frequency command value when T051-T054 [Digital Inx Sel] is set to 1 “Purge”. An
active purge input will override speed command as shown in the flowchart on
Values
Default:
5.0 Hz
Min/Max:
0.0/320.0 Hz
Display:
0.1 Hz
A142 [Internal Freq]
Related Parameter(s):
Provides the frequency command to the drive when
[Speed Reference] is set to 1 “Internal
Freq”. When enabled, this parameter will change the frequency command in “real time” using the
digital speed keys when in program mode.
Important: Once the desired command frequency is reached, the Enter key must be pressed to store
this value to EEPROM memory. If the ESC key is used before the Enter key, the frequency will return
to the original value following the normal accel/decel curve.
If
-
[Digital Inx Sel] is set to 16 “MOP Up” or 17 “MOP Down” this parameter acts as the
[Speed Reference] is set to 1 “InternalFreq”.
