5.5 Sequence Chart of Control Signals

In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram:

Remark:

PUL/DIR

 

  1. t1: ENA must be ahead of DIR by at least 5μ s. Usually, ENA+ and ENA- are NC (not connected).
  2. t2: DIR must be ahead of PUL active edge by 6μ s to ensure correct direction;
  3. t3: Pulse width not less than 2.5μ s;
    1. t4: Low level width not less than 2.5μ s.

6. DIP Switch Setting

6.1 Activate Edge Setting

SW1 is used for setting the activate edge of the input signal, “off” means the activate edge is the rising edge, while “on” is the falling edge.

6.2 Running Direction Setting

SW2 is used for setting the running direction, “off” means CCW, while “on” means CW.

6.3 Micro steps Setting

The  micro  steps  setting  is  in  the following table, while SW3 、

SW4 SW5 SW6 are all on, the internal default micro steps inside is activate,this ratio can be setting through the HISU

  1. Appearance and Installation Dimensi
  1. Typical Connection

 

This drive can provide the encoder with a power supply of +5v, maximum current 80mA. It adopts a quadruplicated-frequency counting method, and the resolution ratio of the encoder multiply 4 are the pulses per rotate of the servo motor. Here is the typical connection of

10. Parameter Setting

The parameter setting method of 2HSS86H-KH drive is to use a HISU adjuster through the 232 serial communication ports, only in this way can we setting the parameters we want. There are a set of  best default parameters to the corresponding motor which are care

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

 

There are total 20 parameter configurations, use the HISU to download the configured parameters to the drive, the detail descriptions to every parameter configuration are as follows:

 

 

Item

Description

Current loop Kp

Increase Kp to make current rise fast. Proportional Gain determines the response of the drive to setting command. Low Proportional Gain provides a stable system (doesn’t oscillate), has low stiffness, and the current error, causing poor performances in tracking current setting command in each step. Too large proportional gain values will cause oscillations and

unstable system.

Current loop Ki

Adjust Ki to reduce the steady error. Integral Gain helps the drive to overcome static current errors. A low or zero value for Integral Gain may have current errors at rest. Increasing the integral gain can reduce the error. If the Integral Gain is too large, the system

may “hunt” (oscillate) around the desired position.

Damping coefficient This parameter is used to change the damping coefficient in case of the desired operating state is

under resonance frequency.

Position loop Kp

The PI parameters of the position loop. The default values are suitable for most of the application, you don’t need to change them. Contact us if you have

any question.

Position loop Ki

 

Speed loop Kp

The PI parameters of the speed loop. The default values are suitable for most of the application, you don’t need to change them. Contact us if you have

any question.

Speed loop Ki

Open loop

current

This parameter affects the static torque of the motor.
Close loop current This parameter affects the dynamic torque of the motor. (The actual current = open loop current +

close loop current)

Alarm Control

This parameter is set to control the Alarm optocoupler output transistor. 0 means the transistor is cut off when the system is in normal working, but when it comes to fault of the drive, the transistor

becomes conductive. 1 means opposite to 0.

Stop lock enable

This parameter is set to enable the stop clock of the

drive. 1 means enable this function while 0 means disable it.

Enable Control

This parameter is set to control the Enable input

signal level, 0 means low, while 1 means high.

Arrival Control

This   parameter   is   set   to   control   the   Arrival

optocoupler output transistor. 0 means the transistor is   cut   off   when   the   drive   satisfies   the arrival

command, but when it comes to not, the transistor becomes conductive. 1 means opposite to 0.
This drive provides two choices of the number of

lines of the encoder. 0 means 1000 lines, while 1 means 2500 lines.

The limit of the position following error. When the actual position error exceeds this value, the drive will go into error mode and the fault output will be

activated. (The actual value = the set value× 10)

users can also set the micro steps by the outer DIP switches. (The actual micro steps = the  set value

11. Processing Methods to Common Problems and Faults

11.1 Power on power light off

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

11.2 Power on red alarm light on

n Please check the motor feedback signal and if the motor is connected with the drive.

n The stepper servo drive is over voltage or under voltage. Please lower or increase the input voltage.

11.3 Red alarm light on after the motor running a small

angle

n Please check the motor phase wires if they are connected correctly if not please refer to the 3.4 Power Ports

n Please check the parameter in the drive if the poles of the motor and the encoder lines are corresponding with the real parameters, if not, set them correctly.

n Please check if the frequency of the pulse signal is too fast, thus the motor may be out of it rated speed, and lead to position error.

11.4 After input pulse signal but the motor not running

n Please check the input pulse signal wires are connected in reliable way.

n Please make sure the input pulse mode is corresponding with the real input mode.
