Overview

NDC556 is a digital stepping drive for 42/57 two-phase hybrid stepping motor speed regulation applications that developed by Noketech. The user can set the speed through the DIP switch and has the return double speed control function. Applicable fields: laser, assembly line, convenoy, intelligent logistics etc.

Parameter setting switch description

1) DIP switches SW1-SW3 set the output current of the drive, as shown in the table below:

2) DIP switches SW5-SW8 set the motor running speed, as shown in the table below:

3) DIP switches SW5-SW8 set the motor running speed, as shown in the table below:

Static current can use SW4 DIP switch to set up, on means Static current is the half of dynamic current, off means that the quiescent current is the same as the dynamic current. In general use, SW4 should be set to on to reduce the heat of the motor and drive and improve the reliability.  About 0.4s after the pulse train stops , the current is automatically reduced to about half (60% of the actual value), and the calorific value is theoretically reduced to 36%.

Typical wiring diagram

The standard type of NDC556 adopts 24VDC control signal interface. When the controller is a PLC, it can directly connect the control signal without adding a current limiting resistor. In practical applications, the most typical application method is to use the common anode wiring method as shown in the following drawing:

However, the control signal of NDC556 adopts the optical isolation mode, and the control signal can also be connected in differential mode or common cathode wiring mode according to the user application requirements, as shown in the following drawing:
