527F

The installation of the 527F or 527FX into a Fadal is very easy. But moving too quickly and not reading the instructions or missing steps can lead to frustrations. This post is not to replace the instructions. But it is an encouragement to read the instructions to save time later.

Common mistakes:

1. Not reading the instructions.

2. Not taking enough pictures and videos of the machine before starting. For example pictures of all the parameters, SV, BL, and other screens. Take abundant pictures of each of the cabinets.

3. If installing an optional pendant upgrade, not waiting until the 527F control cards are fully functioning before starting pendant install.

4. Assuming that parameters values transfer exactly to the new control. The SETP parameters are close but not exactly the same, so some of the values will be different. Like most of the "FACTOR" values will be different. Systematically, review each parameter one by…

A "SPINDLE OREINTATION FAILURE" errors can happen if orientating speed is not set correctly for the gear range the failure occurs. Here is a check list for what could be wrong:

1. Check Air (air pressure is required to lock the spindle during orientation)

2. Check that RPM of spindle is same for both M3 and M4

3. Check ORIENTATION FACTOR parameter

4. Check SPINDLE RPM OFFSET parameter

5. Test orientation in all ranges.

The 527F requires the rigid tapping software to be installed, see OPTIONS command to display status.

Next the machine must support rigid tapping see this post to help determine if machine supports rigid tapping:

Basically the setup is 99% the same as the Fadal, the RAMP and GAIN numbers will be typically be a bit different compared to what the CNC88 would end with. Use the instructions attached. You auto tune the drive. Using the Fadal service tool thread you adjust the GAIN and RAMP for the Rigid tapping in SETP:

The velocity of an axis is the rate of change of position: dx/dt

The acceleration of an axis is the rate of change of velocity: dv/dt

The jerk of an axis is the rate of change of acceleration: da/dt

AT ENTER NEXT COMMAND enter diagnostics with the DI command. Then use the AC command, this will show the current max velocities set for each axis and the machine travel (parameters IPM and TRAVEL).
