Design and Performance
24VDC Control Supply for Uninterrupted Safety Backup
A 24VDC input for control allows the drive’s control circuits to remain active even when the main AC supply is removed, eliminating startup routines and providing a safety backup for critical equipment that must always be ready for action.
Obsolete Platform Still Widely Supported for Maintenance
Nidec has officially declared the entire Unidrive SP series obsolete, but the SP2403 remains actively sourced new, refurbished, and via repair-exchange programs for maintenance and like-for-like replacement, avoiding the complications of a full drive system retrofit.
Three Expansion Slots for Full System Flexibility
With room for three plug-in Solution Modules, the SP2403 supports the full range of I/O, PLC/motion, communications (EtherCAT, Profibus DP, DeviceNet, PROFINET, and more), and feedback options available across the Unidrive SP range.
Precision Multi-Motor Control via Keypad Configuration
Using the keypad, the SP2403 can be configured to control induction, asynchronous servo, and synchronous servo motors, with Servo mode providing precision, dynamic control supporting a wide range of rotary and linear motors.
Flexible Surface or Through-Panel Mounting
Unidrive SP drives from size 1 to 6, including the SP2403, can be mounted either on the surface or through the panel with the appropriate brackets, giving installers flexibility to match the mounting method to their specific control cabinet design.
