Unidrive SP AC Drive from Emerson/Control Techniques is a complete drive automation range that covers the power spectrum from 0.5 to 2,900 hp. All drives share the same flexible control interface regardless of the power rating. Drives are packaged in three formats: Panel Mount, Free Standing and Modular. Unidrive SP Panel Mount drives are standard AC input, AC output modules for installation within a control panel. The AC modules are easy to install and commission and can be applied in a wide range of applications. Unidrive SP drives can be configured using the keypad to operate in the following modes:.
Open loop V/Hz AC drive. Open loop Vector AC drive.
Closed loop AC drive. AC servo amplifier for rotary and linear motors. Regenerative (Active) power supply Three Control Techniques click-in option module slots allow the drive to be uniquely customized to your application allowing you to select the level of programmable control, connectivity and I/O you need. Unidrive SP Free Standing drives offer a fully engineered drive that is supplied within a standard sized enclosure.
Control Techniques
Free Standing drives can be ordered to include all of the power input equipment needed to allow immediate connection to the motor and to the power supply. The Unidrive SPM (Modular) AC power modules provide the same advanced control feature set as our Panel Mount AC drives but with additional power system flexibility; the AC drives may be arranged to provide a common DC bus system with or without an active front end (regenerative, 4 quadrant operation). Very high current motors may be controlled using a multi-drive modular arrangement. Part #: Description: Unidrive SP with LED Keypad, 230VAC, 0.5hp, 2.2A Cont.

Unidrive SP Low Voltage DC Installation Guide www.controltechniques.com Issue Number: 1. Environmental limits Instructions in the Unidrive SP User Guide regarding transport, storage, installation and use of the drive must be complied with, including the specified environmental limits. Drives must not be subjected to excessive physical force.
Principles of operation The Unidrive SP is normally operated from a 3-phase AC supply (200V, 400V etc.) or a DC supply of the equivalent rectified voltage. Use your mind quotes. This provides power for all control circuits via the SMPS (Switch Mode Power Supply), and power for the motor via the inverter. For Unidrive SP sizes 1 to 6, a 24Vdc supply must be connected to the +24V external input on the green control terminal block of the drive (see Chapter 4 System design ).
This supplies the control circuitry and may be connected permanently. 2.4.2 Operation with a servo motor When in Low Voltage DC operation the Unidrive SP may NOT be able to limit the speed of a servo motor with an overhauling load.
WARNING If a permanent magnet motor is made to rotate at a high enough speed by an external torque, the DC bus of the drive and its associated wiring could rise above the lower voltage DC operating level. Ratings 3.1.1 Drive output current ratings For drive output current ratings please refer to the Unidrive SP User Guide. 3.1.2 Low Voltage DC rating On all but size 1, the applied Low Voltage DC supply level is set by the user in Pr 6.46. Minimum and maximum voltage values include ripple and noise.
Ripple and noise levels must not exceed 5%. A common supply can be used for the drive control 24V and 24V Low Voltage DC mode NOTE enable. Unidrive SP Low Voltage DC Installation Guide www.controltechniques.com Issue Number: 1. DC bus and trip the drive should it drop below normal operating levels with a charged battery. SM-Applications module used: A software trap should be added to prevent this loop from occurring. Unidrive SP Low Voltage DC Installation Guide Issue Number: 1 www.controltechniques.com. The wiring from the fuse to the supply must be rated correctly for the supply.
External softstart resistor When Unidrive SP size 1 to 3 operates from AC or DC there is a built in soft start resistor to limit the inrush current. However when Unidrive SP size 4 and larger operate from Low Voltage DC there is no inbuilt soft start resistor and therefore an external soft start resistor is required between the Low Voltage DC supply and the drive. 4.6 System configurations. Pr 6.44 indicates which supply the drive is currently operating from: 0 = Normal high voltage supply 1 = Low Voltage DC supply. Unidrive SP Low Voltage DC Installation Guide Issue Number: 1 www.controltechniques.com. This system configuration is suitable for systems were the power supply cannot absorb any energy from the load through the drive, hence the reason for blocking diode D1 being fitted in series with the DC supply.

Table 5-2 Recommended Low Voltage DC supply fuse current ratings (Unidrive SP size 4 to 6, SPMA/D) The fuse voltage rating must be suitable for the rectified drive AC supply voltage, e.g. ≥400Vdc for a SPx20x, ≥750Vdc for a SPx40x, ≥890Vdc for a SPx50x, and ≥1000Vdc for a SPx60x.The chosen thermal overload relay must have a class 10 trip characteristic. High temperatures The discharge resistor can reach high temperatures. Locate the resistors so that damage cannot result.
Use cable having insulation capable of withstanding high temperatures. WARNING Unidrive SP Low Voltage DC Installation Guide www.controltechniques.com Issue Number: 1.
