      $89 SureStep Stepper Drive

• Standard Stepper Drives
• Standard stepper drive - STP-DRV-4035
• Standard stepper drive - STP-DRV-6575 ... New! and only $89
• Standard high-speed pulse input (pulse and direction)
• On-board or removable screw terminals for easy hook-up
• Optically-isolated inputs ready for +5VDC logic or 5–24 VDC available
• No software or add-on resistors required for drive configuration; dipswitch and/or rotary-dial set-up
• Dipswitch used for built-in self-test, microstep resolution selection, current level selection, and optional idle current reduction
• Advanced Stepper Drives
  The advanced drives can operate with traditional high-speed inputs, but can also be commanded via 0–5V analog input. They have an internal indexer that can accomplish point-to-point moves controlled via ASCII communication.
• Advanced stepper drive - STP-DRV-4805
• Advanced stepper drive - STP-DRV-80100
  All the features of the standard drives, plus:
• Software configurable
• 200 - 51,200 microsteps (software selectable)
• High-speed pulse input (Quadrature, cw/ccw, pulse/direction)
• Analog velocity mode (0-5v or potentiometer)
• Internal indexer (point-to-point moves via ASCII command)

• Four Linear Power Supplies
• STP-PWR-3204 (32 VDC @ 4A)
• STP-PWR-4805 (46.5 VDC @ 5A)
• STP-PWR-4810 (46.5 VDC @ 10A)
• STP-PWR-7005 (70 VDC @ 5A)
• Power Supply Features
• 120/240 VAC selectable input
• 32V, 48V, 70V DC output models available
• All models have additional 5VDC, 500 mA regulated logic supply
• Fusing included for both incoming AC and outgoing DC
• 5V supply has electronic overload protection

• For Advanced Stepper Drives
  (software is NOT required for the standard drives)
• SureStep Pro configuration software is also available on CD (STP-PRO)
• Spare/replacement programming cable STP-232RJ11-CBL is available
• Used for easy configuration and setup of the stepper drive system; including drive, motion control mode, I/O, stepper motor
• Serial command language for motor drive control via serial port; eliminates the need for separate motion controllers or indexers; provides easy interface to other industrial devices such as PCs, PLCs and HMIs.
• Easily use the ASCII output commands from most of our PLCs to enable indexing capability
• Help files include technical data, application information, advanced setup, serial command instructions
• Runs on 32-bit/64-bit Windows 7, Vista, XP

• These accessories dissipate energy that feeds back into the drive system when the motor is being pushed by the load.
• Application examples include suspended (or hanging) loads and large masses that have to be stopped / decelerated quickly.
• These type loads cause energy to be pushed back into the motor and drive. If this energy is not dissipated, the drive's DC voltage will increase until the drive trips on Over Voltage.
• The regeneration clamp monitors any feedback voltage and automatically "dumps" this excess energy into the built-in and/or external braking resistors.

• Built-in 50W power resistor for more continuous current handling (optional 100W resistor is also available)
• Mounted on a heat sink
• Voltage range: 24–80 VDC; no user adjustments required
• Power: 50W continuous; 800W peak
• Wire connection: 6-pin screw terminal block; 12–18 AWG wire
• Indicators (LED):
  - Green = power supply voltage is present
  - Red = clamp is operating (usually when stepper is decelerating)
• Protection: The external power supply is internally connected to an "Input Diode" in the regen clamp that protects the power supply from high regeneration voltages. This diode protects the system from connecting the power supply in reverse. If the clamp circuit fails, the diode will continue to protect the power supply from over-voltage.
