Specifications

Leadshine’s iST-2320 integrated stepper is a NEMA23 stepper motor integrated with an advanced DSP stepper drive. At very compact size and with all components integrated, the iST-2320 can save mounting space, eliminate motor wiring time, reduce interference, and cut/reduce cable and labor costs. By adopting Leadshine’s latest current control technology, the drive of theiST-2320 can drive the stepper motor with high precision, smooth movement, and extra low noise at low speed movement with no obvious resonance area.

Micro Step Resolution (S1-S4)

 

 

Micro step resolution of the iST-23xx can be configured via DIP switch S1-S4 or Leadshine’s tuning software ProTuner. When all S1-S4 are at “ON” positions, the drive will take the micro step resolution setting set by the software (4000 by default). In this case, a user can re-configure the resolution to any value between 200 and 512,000 (increased by 1) through software. If any bit of S1-S4 is at “OFF” position, the integrated drive board will take micro step resolution setting determined by bit positions of S1-S4. Use the following table for their resolution settings via the DIP switch.

Motor Shaft Direction (S5)
 

 

DIP switch S5 is used for changing motor shaft rotation direction. Changing position from “ON” to “OFF”, or “OFF” to “ON” will reverse rotation direction of the iST-23xx.

 

 

Self-Test (S6)
 

 

By default, DIP switch S6 is OFF (Normal Mode) and the iST-23xx responses to any pulse input. If it is turned ON, the iST-23xx goes into self-test mode. In self-test mode, the motor shaft rotates 1 revolutions CW and then 1 revolutions CCW. The self-motion repeats until S7 is turned OFF (the motor shaft will stop immediately). Note that you are unable to communicate with the iST-23xx via the RS232 port when it is in self-test mode.

 

Leadshine’s iST-23xx has three connectors, a connector for power connections, a connector for control signals connections and a connector for RS232 communication connections.

Description

PUL+

I

Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, active at each rising or falling edge (software configurable). In double pulse mode (software configurable), this input represents clockwise (CW) pulse, active both at each high level and low level. 4.5-24V for PUL-HIGH, 0-0.5V for PUL-LOW. For reliable response, pulse width should be longer than 2.5μs for 200K MAX input frequency or 1μs for 500K MAX input frequency.

PUL-

DIR+

I

Direction Signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation. In double-pulse mode (software configurable), this signal is counter-clock (CCW) pulse, active both at high level and low level. For reliable motion response, DIR signal should be ahead of PUL signal by 5μs at least. 4.5-24V for DIR-HIGH, 0-0.5V for DIR-LOW. The motor direction can also be changed by DIP switch S5.

ENA+

I

Enable signal: This signal is used for enabling/disabling the drive board. By default, high level (NPN control signal) for enabling the drive board and low level for disabling the drive board. It is usually left UNCONNECTED (ENABLED). Please note that the PNP and Differential control signals are on the contrary, namely Low level for enabling. The active level of ENA signal is software configurable.

Alarm Signal: OC output signal, activated when one of the following protection is activated:over-voltage and over current error. They can sink or source MAX 20mA current at 24V. By default, the impedance between ALM+ and ALM- is low for normal operation and becomes high when any protection is activated. The active impedance of alarm signal is software configurable.
