In 2013, Control Techniques launched a new range of industrial AC drives called Unidrive M.  Unidrive M’s design is based on the success and popularity of the Commander SK, and incorporates market-leading technologies.

Unidrive M: compatibility with Commander SK 

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 

Parameters
• The same menu and parameter structure is adopted by Unidrive M
• Unidrive M Connect can be used to transfer parameters from Commander SK to Unidrive M 

Software programs
• The SI-Applications Plus option module can compile SyPTPro programs for Unidrive M

Commander SK transitioned to become a legacy product in 2015, which means they can be subject to price and lead time changes as volume production reduces. The legacy period is expected to last for two years and will be followed by the maintenance period. With the Commander SK now in the maintenance period of it’s lifecycle, volume production of the product will cease, but contractual obligations regarding warranty, service and repairs will continue. The maintenance period is expected to last ten years subject to raw material and component availability. Updates will be issued to customers throughout the lifecycle period.

Performance InnovationsProgramming and Software Innovations
Unidrive M200-M300 have a new Rotor Flux Control
(RFC) mode which improves motor control and stability
and delivers higher overload currents by using a closed
loop current control algorithm
Patented fan intelligence controls the fan speed in order
to optimize Unidrive M’s cooling profile, save energy and
extend fan life, while keeping audible noise to a minimum
• Transfer parameters without mains power
– New AI-Backup adaptor option can be used
to power the drive with 24 Vdc to maintain
communications and interrogate parameter
settings
– Standard SD cards can be used with AI-Backup
adaptor to transfer and clone parameter sets
• New LCD keypads have informative, multi-language, 3
line displays to make set up and diagnosis easier and
faster
– Remote keypad – Rapid panel mount (1 x 32Ø
hole) IP66 (M200-M300 with AI-485 adaptor)
• Unidrive M200 - M300 incorporates an onboard PLC
which can execute Machine Control Studio (IEC61131-
3) programs for logic and sequencing with real-time tasks – removing the need for additional PLCs
Hardware Innovations
• Simple speed adjustment can be achieved on M101 throughthe onboard potentiometer
• Unidrive M101-M300 can survive environments as described by IEC60721-3-3 3C3 and EN60068-2-60 Meth. 4
– PCBs are conformal coated for increased resilience to conditions and greater reliability
– A patented air duct system protects critical components from environmental contamination
– The IP rating has been increased from IP20 to IP21
• Higher level of integration with machine safety systems.
Unidrive M300 has a dual channel ‘Safe Torque Off’ (STO) inputs which conform to SIL3/PLe
• New cable management design: a new metal bracket support has been created
