Hello all,

I've decided to retrofit my Cyclone following a servo problem. My X axis servo has a fault with the encoder and is not repairable, so I am replacing the original motors, drives and control with new kit.

I have the following available for spares:

Computer module with mint card, spindle card and additional I/O board.
2 x Parker BL30 drives,
1 x working Parker ML2340 servo, 1 x faulty servo (might be of use for parts?)
1 x transformer for the drives,
complete VDU and keyboard assembly, with cable and connectors, all very good working condition.
Various cables etc that relate to the above.

Anyone who is interested, please PM me.

Out of curiosity, do the servo motors have a spec (torque/voltage/current/wattage) on them?
Also, was there any gearing between the servo and ball screw?

I opted for a 400W (1.27Nm cont with a 10:16 belt ratio) and 700W (2.4Nm Cont with a 1:1 ratio) when I retrofitted my Cyclone, and am just wondering how they compare to the original servo cyclones, as mine was a stepper version.

The servo's are quite modest really, I believe the bus voltage from the drives is 85v and the continuous torque is around 0.7Nm. Continuous current rating is 3.75A, which makes the power around 320W, ish. I'm replacing with 400W AC servo's, they are rated nearly double the torque of the original Parker, probably only half the lifespan though. My pulley arrangement is 1:1 on both X and Z, X being 18:18 teeth and Z being 16:16 teeth.

I'm sure your 700W servo has bags of torque!
