ACH580 E-Clipse bypass and packaged drive user manual 39
E-Clipse bypass functions overview
Initial Programming for Override function using OVRD2, via parameters
Only required for E-Clipse parameter selections:
1708, OVRD2 MODE [2] VFD or [3] VFD/BYPASS
The drive should first be set up and operating
correctly with the E-Clipse Bypass.
ACH580 Parameters
The parameters in this section program the ACH580 VFDs operation during Override Mode.
Parameter Parameter Name Parameter Value Comments
95.21 HW option word 2 Bit 5: Bypass present
Bit 8: Legacy bypass
present
Verify that the Drive is set up for E-Clipse
bypass. Word value for 95.21 = [1] E-Clipse
bypass is = 0010 0000.
70.02 Override enable [0] Off
[1] On
[2] On, critical
Default is [0] Off
• Off: Override is not being used,
• On: Uses programmed number of fault
resets,
• On, Critical: infinite number of fault
resets.
70.03 Override activation source [5] DI5 high Contacts closing against the drive’s DI5 will
activate Override Mode in the ACH580 VFD.
70.04 Override reference source [0] Constant speed/freq
[1] AI1
[2] AI2
[3] Override speed/freq
[4] Motor potentiometer
[5] Stop
[6] Process PID set1
Defaults to [3] Override speed/freq
The drive will use the Hz value programmed
in 70.06
Note that [0] Constant speed/freq is similar
70.05 Override direction [0] Forward
[1] Reverse
[2] to [7], DI1 to DI6
[8] to [13], -DI1 to -DI6
[9] Other
Defaults to [0] Forward
70.06 Override frequency -500 Hz to 500 Hz Defaults to 0.0 Hz. Set the value the drive
will control to in Override when 70.04 is [3].
