3.6.1. Parameter Setup and Hardware Configuration
Setup for the Voltage-to-Current mode should be performed using the Automation 3200
SMC. This software interface should be used to configure the parameters on the drive.
The parameters of principal concern are:
!
Current Loop Parameters (gains, offsets, etc.)
!
Feedback configurations (feedback types, channels, etc.)
!
Commutation Information (pole pairs, counts per cycle, etc)
!
Current Clamp/RMS Current Trap
These are the parameters that will need to be saved to the flash memory within the
Ndrive HL, before the standalone mode is activated. To enter the normal, A3200
operating mode, power down the drive and set DIP switches #6 and #7 to the ON
position.
Once the parameters are correctly configured to run the motor with the A3200 (and
verified) they can then be saved to the flash memory.
This initial setup should only need to be performed once
for a given system type. If the parameter settings for a
given axis in the system have already been verified, then
on all future systems the A3200 software can be used to
load the parameters for that axis into the Ndrive HL/HP so
that they can be saved to the flash memory on that drive.
Re-configuration should only need to be done for a
different system, or if it is expected that some other system
parameter may have changed.
3.6.2. Saving Parameters to the Flash Memory on the Drive
Open the Ndebug.exe utility and select the axis (by typing AX n, where n is the 1-based
axis number, of the axis you wish to select). Save the parameters to flash memory by
typing:
FLASHWRITE 1 0 0
This will save the current system configuration into the flash memory on the Ndrive HL.
To enter the voltage-to-current mode, power down the Ndrive and set DIP switches #6
and #7 to the OFF position. When the unit is powered on again, it will auto-boot into the
voltage-to-current mode.
