That's correct. I'm going to try to adjust the gain settings and see if I can get this tighter. Any suggestions what settings to look for? Many thanks

Probably need the drive manual for that...
If it's like a classic motor drive, there will be three nested PID loops:
1. Torque (current) command/feedback --> torque (current) out
2. Velocity command/feedback --> torque out
3. Position command/feedback --> velocity out
Is there any tuning program available for the drive?

I have had a good look through the manual, unfortunately, no tuning software but i have looked at these parameters and looks like they can help.
P08-00 Speed loop gain.
P08-01 Speed loop integral time constant
P08-2 Position loop gain
P08-15 Load inertia ratio
P08-19 Speed feedforward gain
P08-00 Speed loop gain.
P08-01 Speed loop integral time constant
P08-2 Position loop gain
P08-15 Load inertia ratio
P08-19 Speed feedforward gain

Yep, I think you normally tune the inner (velocity in this case) loop first
