Dynamic Current Setting; Standstill Current Setting; Motor Auto-Identification And Parameter Auto-Configuration; Typical Connection - Leadshine Technology MA860C User Manual

5.2.1 Dynamic Current Setting

Peak Current
2.40A
3.08A
3.77A
4.45A
5.14A
5.83A
6.52A
7.20A
Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting,
Notes:
particularly under high speed condition.

5.2.2 Standstill Current Setting

SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current,
and ON meaning that standstill current is set to be the same as the selected dynamic current.
The current automatically reduced to 50% of the selected dynamic current one second after the last pulse. If the
application needs a different standstill current, please contact Leadshine.

5.3 Motor auto-identification and parameter auto-configuration

The drive will operate the function of motor auto-identification and parameter auto-configuration when power on, and
calculate the optimal parameter using for current control after this processing,, then the stepper motor can output
optimal torque.

6 Typical Connection

A complete stepping system should include stepping motor, stepping drive, power supply and controller (pulse
generator). A typical connection is shown as figure 10.
