Overview
NDC860IO- is a medium-voltage speed-regulated driver for the 86 series two-phase hybrid motor that developed by Noketech, with a built-in control pulse transmitter. It adopted advanced digital filtering technology, anti-resonance technology and real-time precision current control technology to make it realize precise smooth operation, extra low noise. It’s especially suitable for assembly line, conveyor, intelligent logistics field.
Adoptive motor: 86 full series two-phase hybrid stepping motor.
1）Working (dynamic) current setting
Output peak current | Output average current | SW1 | SW2 | SW3 |
2.40A | 2.00A | on | on | on |
3.08A | 2.57A | off | on | on |
3.77A | 3.14A | on | off | on |
4.45A | 3.71A | off | off | on |
5.14A | 4.28A | on | on | off |
5.83A | 4.86A | off | on | off |
6.52A | 5.43A | on | off | off |
7.20A | 6.00A | off | off | off |
2）Quiescent (static) current setting
Static current can be set by SW4 DIP switch, on means that 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 100ms 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%.
3）Motor running speed setting
NDC860IO is a speed-regulated two-phase hybrid stepping driver that can set the running speed of the motor through a DIP switch. The specific settings are shown in the following table:
Speed | SW5 | SW6 | SW7 | SW8 |
10 | on | on | on | on |
20 | off | on | on | on |
30 | on | off | on | on |
40 | off | off | on | on |
50 | on | on | off | on |
60 | off | on | off | on |
70 | on | off | off | on |
80 | off | off | off | on |
90 | on | on | on | off |
100 | off | on | on | off |
120 | on | off | on | off |
140 | off | off | on | off |
160 | on | on | off | off |
180 | off | on | off | off |
200 | on | off | off | off |
250 | off | off | off | off |

3. The way to improve heat dissipation
1）Usually, the reliable working temperature of the drive is within 60℃, and the working temperature of the motor is within 80℃.
2) In order to reduce the heat of the motor and drive, it is recommended to select the automatic half-current mode when using that the current decreases by half automatically when the motor stops.
3）When installing the driver, please install it vertically and sideways, so that the heat sink teeth forms strong air convection; when necessary, install a fan near the drive for better heat dissipation, to ensure that the drive works within a reliable operating temperature range.
