DIP Switch Setting

Introduction Of SW-2

Current Setting

The SW-2 current setting is in the following table.

Standstill current Setting

SW4 is used for setting the standstill current , “off” means the standstill current is set to be half of the selected dynamic current or other current, which can be set by the HISU, the details can be seen in the tenth sections. While “on” means the standstill current is set to be the same as the selected dynamic current.

Micro steps Setting

The micro steps setting is in the following table. And the micro steps can be also setting through the HISU. The details can be seen in the tenth sections.

SW-2 micro steps setting is in the following table

Introduction Of SW-1

The SW-1 switch is mainly a number of auxiliary functions, the auxiliary functions of the first three switch are respectively motor self detection, pulse counting mode and single pulse selection; Fourth and fifth are set for the smoothing coefficient, and the last one is reserved.

Parameter Setting

The parameter setting method of 2DM556S drive is to use a HISU adjuster through the 232 serial communication ports, only in this way we can set the parameters we want. There are a set of best default parameters to the corresponding motor which are carefully adjusted by our engineers, users only need refer to the following table, specific condition and set the correct parameters.

Actual value = Set value × the corresponding dimension

Processing Methods to Common Problems and

Faults

Power on power light off

• No power input, please check the power supply circuit. The voltage is too low.

Power on red alarm light on

• Please check the motor is connected with the drive.
• The stepper digital drive is over voltage or under voltage. Please lower or increase the input voltage.

After input pulse signal but the motor not running

• Please check the input pulse signal wires are connected in reliable way.
• Please make sure the input pulse mode is corresponding with the real input mode.
• The Driver is disabled.
