Digital Microstep Driver CS2RS-D507

  • Support for Modbus RTU protocol (RS485)
  • Input: 20 to 50 VDC; Output: 1.0 to 7.0A
  • Integrated heatsink and connector included
  • Software for setting parameters on PC: Leadshine Motion Studio
  • 7 programmable inputs: Limit (+/-), origin, quick stop, alarm acknowledgment, Enable, JOG input (+/-) and Position table
  • 3 programmable outputs: Alarm, Brake, and homing / Instruction / completed run
  • Operating modes: speed, position, homing
  • Function support: learning, interruption, jump, suspension, movement of traffic
  • Very low noise; Low heat dissipation; very smooth movement even at low speed
  • No step loss, no hunting, no torque reservation
  • Anti-resonance system for optimum torque over the entire speed range
  • Protection against over voltage, over current, phase errors, position tracking errors and encoder cable errors.
  • Configuration by 8 micro-switches
  • CE and ROHS certified
The CS2RS series offers closed-loop step-by-step drivers based on the standard Modbus RTU protocol, using RS485 communication to network up to 31 axes, integrated PR function with 16-segment position table (PR mode).
Not only can they solve the problem of step loss in the open-loop stepper system, but also avoid the need for additional controllers in most point-to-point applications, to significantly improve system reliability and reduce costs.
The CS2RS series also supports learning function, operating modes in position profile, speed profile and homing.

Usable with NEMA 17, NEMA 23 and 34 size motors, this driver is particularly recommended for 2-phase motors of the CS-M ... series in the SOPROLEC range, that have an integrated encoder with a resolution of 1000 to 5000 pulses per revolution.
Used in placement applications and XY tables, this driver will bring you optimum operation with reduced noise.

Parameter setting by serial RS232 link allows optimum adjustment of the driver settings.

DIP Switches

The CS2RS drivers  uses 8 bits for configuration (via 8 DIP Switches), to define Slave ID (also known as "Site Alias"), as well as a terminal resistor, as follows :

Slave Driver position setting : SW1 to SW5

Slave ID SW1 SW2 SW3 SW4 SW5
1 (Default) on on on on on
1 off on on on on
2 on off on on on
3 off off on on on
4 on on off on on
5 off on off on on
6 on off off on on
7 off off off on on

Baud Rate : SW6 -SW7

Baud Rate SW6 SW7
115200 on on
38400 (Default) off on
19200 on off
9600 off off
When SW6-SW7 are on OFF position,  Baud Rate can be set by the PC software.

Terminal Resistor selection: SW8

SW8=ON: terminal resistance is valid;
terminal resistance is invalid(Factory setting)

The last slave driver of the network must be connected to a 120Ω resistor, and this means its SW8 switch must be set to ON.
