Upgrading from Unidrive SP to Unidrive M
Variable frequency drives for high performance Unidrive M600 and Unidrive M700 offer significant enhancements over Unidrive SP. Improvements have been made to performance, hardware, programming and software.
-
Compatibility
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 Unidrive SP
Parameters
- The same menu and parameter structure is adopted by Unidrive M
- Unidrive M connect can be used to transfer parameters from Unidrive SP to Unidrive M

Performance
Performance Innovations
-
Unidrive M600 and M700 improve productivity with enhanced motor control algorithms which are combined with the latest microprocessor technology
-
More than double the current loop bandwidth for demanding performance applications
-
New sensorless control of permanent magnet motors for applications that require maximum efficiency and reduced motor size
-
Maximize machine throughput with an onboard Advanced Machine Controller (AMC) which can be easily set up to deliver faster, more precise, dynamic machine operation
-
Integrated dual port Ethernet switch which supports Ethernet I/P as well as standard Ethernet open protocols such as TCP/IP and UDP
-
RTMoE (Real Time Motion over Ethernet) provides synchronized communication between drives using the Precision Time Protocol as defined by IEEE1588 V2
-
Faster switching frequencies of up to 16 kHz in systems up to 160 kW (250 hp) and 8 kHz in systems up to 250 kW (400 hp)

Programming and Software
Programming and Software Innovations
-
MCi200 and MCi210 options provide advanced second processors to execute PLC programs for multi-axis machine control. Programs can be created quickly and easily using Engineering Control Studio
- Unidrive M supports standard SD cards for cloning and backing up parameters and application programs
-
Keypads are equipped with multi-lingual real-text displays to provide faster, easier programming with helpful descriptions of diagnostic information and drive parameters
-
SI-Applications modules compile and run SyPTPro application programs. This assists the migration of standalone applications as well as Unidrive SPs that form part of a CTNet or CTSync network
-
Unidrive M has a menu and programming structure that is consistent with Unidrive SP
-
Parameter sets can be transferred from SP to M using the Unidrive M Connect software tool and Smartcards
-
Hardware
Hardware Innovations
-
Higher power range – Unidrive M modular systems can now reach 2.8 MW with up to 250 kW in a single power module
-
A low switching frequency of 2 kHz can be selected to maximize the output power of large drives
-
Unidrive M’s DC bus schemes use a dedicated bus bar arrangement for side-by-side mounting and can eliminate the need for many power input components
-
Unidrive M has conformal coated PCBs to ensure increased resilience in harsh environments
-
Greater onboard encoder connection flexibility eliminates the need to purchase additional encoder or resolver option modules. Universal encoder port has been extended to enable two inputs, more encoder types and a simulated encoder output
-
Higher power density with more compact drives
-
A new low power standby mode to reduce energy usage when Unidrive M is idle
-
Unidrive M702 has a dual channel SIL3/PLe ‘Safe Torque Off’ (STO) input
