Product Description

1SU11001 is a single phase SP500 drive manufactured by Reliance Electric. The drive has a NEMA 1 enclosure, size A. The NEMA 1 enclosure is vented and is designed for general-purpose indoor applications. This drive has an AC input of 115 volts, an input of 13.1 amps and 1.5 KVA, an output of 6.8 amps, and a power loss of 80 watts. The horsepower is 1 HP.

The SP500 drive manual is designed to be used only by qualified electrical personnel. The drive features a 500 millisecond power dip ride through, 150% overload for one minute, 0.5 to 240 Hz 3-phase voltage output, a UL/CSA electronic overload that meets NEC/CEC requirements, quiet motor operation with high carrier frequency selection, either a NEMA 1 or NEMA 4X/12 enclosure, and drive protection against overcurrents, short circuits, ground faults, overvoltage, undervoltage, and overtemperature. This drive offers 29 user-adjustable software parameters; user-selectable relay contact for indications of drive running, drive faulted, or drive at selected speed; user-selectable local or remote operation; user-selectable power-up start, auto-restart, and coast-to-rest or ramp-to-rest stop functions. The drive also offers an on-board keypad and display, which provides a Start/Stop/Reset control, a Forward/Reverse setting, drive diagnostics, a setpoint adjustment, a Motor RPM, percent load, or output voltage display. Lastly, the drive provides a snubber resistor braking signal and a scaled voltage analog output (o to 10 VDC), which is proportional to the output frequency, the output amps, the output voltage, and the selected reference.

Frequently Asked Questions about 1SU11001

Do all SP500 drives operate on a single-phase power?
No. SP500 drives are AC pulse-width-modulated inverters that can operate on either a single-phase or a three-phase power mode. The 1SU11001 SP500 drive operates on a single-phase power.
Are there many faults with the Reliance Electric SP500 1SU11001 drive?
The 1SU11001 drive was made to fix itself. It operates on a coast-to-rest stopping mode to provide ultimate satisfaction. Instead of simply notifying you when a fault occurs, the 1SU11001 drive initiates an instantaneous electronic trip (IET) signal to turn off the drive. Once the 1SU11001 SP400 comes to a coast-to-rest stop, you can reset the drive via a STOP/RESET key or a user-supplied IET RESET button. The 1SU11001 drive was made to operate trip-free under any condition and any faults that may occur are stored in the drive after the drive has reset itself, which can be viewed later on the four-character display.
How can AX Control sell SP500 1SU11001 drives when they have been discontinued by Reliance Electric?
Even though 1SU11001 drives aren't made by Reliance Electric anymore, AX Control has been able to buy out unused 1SU11001 SP500 drives that were never sold in factories. AX Control also refurbishes SP500 drives that can turn out to be more affordable and just as good as new.
What are some measures I should take to install the 1SU11001 drive that may differ from installing other SP500 drives?
Because the 1SU11001 SP500 drive is a NEMA 1 or Chassis enclosure type, there are more preparation measures to make note of. Make sure to ensure that your 1SU11001 drive can be kept clean, cool, and dry and don't place your drive around any type of oil, coolant, or other airborne contaminants. NEMA 1 SP500 drives are more sensitive than other SP500 drives so it is important that you are aware of the surroundings in which your drive is operating under.
What is the difference between program mode and monitor mode on the 1SU11001 drives?
In program mode, your 1SU11001 drive can display parameter numbers, parameter values, and error log information. In monitor mode, your SP500 1SU11001 drive displays different data such as: RPM, Load Percentage, Voltage, and Percent Selected Speed Reference. Monitor mode is the default mode for the 1SU11001 drive, but program mode is preferred by users when the drive is stopped.
