Parameter 58 – D/A #1 Command Value (D/A 1 Cmd Val) *
This parameter displays the actual value input to D/A Converter 1.
Parameter Type: View only in Maintenance level
Minimum Value: –2047
Maximum Value: +2047
Parameter 59 – D/A #2 Command Value (D/A 2 Cmd Val) *
This parameter displays the actual value input to D/A Converter 2.
Parameter Type: View only in Maintenance level
Minimum Value: –2047
Maximum Value: +2047
Parameter 68 – Bandwidth Maximum (Bandwidth Max.) *
After an auto tune, this parameter displays the maximum system bandwidth
that can be achieved with the machine mechanics.
Parameter Type: View only in Modify level and Maintenance level
Minimum Value: 0 rads/second
Maximum Value: 250 rads/second
To convert rads/second to Hertz, divide by 6.28.
Parameter 69 – Auto Tune Friction (Auto Tune Friction)*
The system friction as measured by the auto tune cycle is represented
through this parameter.
Parameter Type: View only in Modify level and Maintenance level
Minimum Value: 0%
Maximum Value: 100% = rated motor current
Parameter 128 – EEprom Functions (EEprom Func)
This parameter allows the user to initialize, recall or save the parameters
stored in the EEprom. Entering the number listed will cause the drive to
perform the designated action.
Parameter Type: View/modify in Modify level and Maintenance level
0 Exit – exit EEprom functions
1 Initialize* – load the default parameters into EEprom
2 Recall – load the drive with the current EEprom values
3 Save – save the current drive parameters to EEprom
*Important: initializing the EEprom will convert all parameters to default values – all previous
values will be lost.
Parameter 129 – Units Select
Allows selection of “User Units” or “Per Unit Values.”
Important: All values shown in this manual are “User Units.” Changing
this parameter is not recommended.
Parameter Type: View/modify in Maintenance level
Default Value: 0 User Units
0 User Units
1 Per Unit
