Unidrive M: compatibility with Commander SK and Unidrive SP

Mechanical

• Compatible physical dimensions, weights and surface mount footprint.
• When retrofitting surface mount drives, existing mounting holes can be reused-negating the need for additional drilling. Mounting holes are in the same place or retrofit kits are available.

Electrical

• Power and control wiring adopt the same philosophy as Commander SK and Unidrive SP.
