VLT® AutomationDrive EZ FC 321
Programming Guide
Parameter 5-70 Term 32/33 Pulses Per Revolution
Table 332: Parameter 5-70 Term 32/33 Pulses Per Revolution
5-70 Term 32/33 Pulses Per Revolution
Default value: 1024
Conversion index: 0
Set the resolution of the encoder connected to terminal 32/33 in pulses per revolution.
Parameter 5-71 Term 32/33 Encoder Direction
Table 333: 5-71 Term 32/33 Encoder Direction
5-71 Term 32/33 Encoder Direction
Default value: [0] Clockwise
Conversion index: –
This parameter cannot be adjusted while the motor is running.
Change the detected encoder rotation direction without changing the wiring to the encoder.

4.6.8 5-8* I/O Options

Parameter 5-80 AHF Cap Reconnect Delay
Table 334: Parameter 5-80 AHF Cap Reconnect Delay
5-80 AHF Cap Reconnect Delay
Default value: 25 s
Conversion index: 0
Guarantees a minimum off-time for the capacitors. The timer starts once the AHF capacitor disconnects and has to expire before the
output is allowed to be on again. It only turns on again if the drive power is 20–30%.

4.6.9 5-9* Bus-controlled

This parameter group selects digital and relay outputs via a fieldbus setting.
Parameter 5-90 Digital & Relay Bus Control
Table 335: Parameter 5-90 Digital & Relay Bus Control
5-90 Digital & Relay Bus Control
Default value: 0
Conversion index: 0
This parameter holds the state of the digital outputs and relays that is controlled by bus. A logical 1 indicates that the output is high
or active. A logical 0 indicates that the output is low or inactive.
