ASDA-M Chapter 7 Motion Control

Revision December, 2014

7-29

7.9.2 Programming the Path in PR Mode

1) Sequence command

Path 1: is AUTO and has set DLY

Path 2: does not set INS

(DLY starts to count after completing

the command)

Path 1: speed command and has set DLY

Path 2: position command

(DLY starts to count after completing the

command)

2) Overlap

Path 1: has set OVLP but cannot set

DLY

Path 2: does not set INS

3) Internal interrupt

Path 1: AUTO and has set DLY

Path 2: has set INS

(DLY is effective to the internal

interrupt)

It can be used to pre-constitute

complicated Profile

4) External interrupt

Path 1: AUTO or SINGLE

Regardless the setting of DLY

Path 2: has set INS

(DLY is ineffective to the external

interrupt)

Profile can be changed from external

any time

Path 2

DLY 1

Speed 1

Path 1

What causes regeneration error in Delta Servo Drives?
- K
  Kayla SmithAug 27, 2025
  A regeneration error in Delta Servo Drives can be caused by several factors: selecting the wrong regenerative resistor or having an unconnected external regenerative resistor (reconnect the resistor or calculate the correct value; if the problem persists, contact Delta or your distributor), failing to set parameter P1-53 to zero when no regenerative resistor is in use (set P1-53 to zero), or incorrect parameter settings (reset the values of P1-52 and P1-53 correctly).

How to troubleshoot undervoltage on Delta ASD-M-0721-F?
- R
  Ryan BurnsAug 27, 2025
  If you're experiencing an undervoltage error with your Delta Servo Drives, there are a few things to check. First, ensure that the input voltage of the main circuit is within the rated allowable voltage by re-confirming the voltage wiring. Also, verify that the main circuit has power supply by checking the power switch. Finally, make sure you're using the correct power input for your system by applying the correct power supply or serial adapter.

Why is my Delta ASD-M-0721-F Servo Drives showing overload?
- B
  Brady ArmstrongAug 26, 2025
  An overload error in your Delta Servo Drives can occur for several reasons. It may be due to exceeding the drive's rated load or continuous excessive use (increase the motor capacity or reduce the load). The control system parameter settings might be inappropriate (adjust the gain value of the control circuit, or slow down the acceleration/deceleration setting time). Also, check for incorrect wiring of the motor and encoder (correct the wiring). If these steps don't resolve the issue, the motor encoder may be defective (contact Delta or your distributor).

What to do if Delta ASD-M-0721-F Servo Drives show overvoltage?
- H
  Holly NixonAug 25, 2025
  If your Delta Servo Drive displays an overvoltage error, the issue might stem from a few potential causes. It could be that the input voltage of the main circuit is higher than the allowable voltage (apply the correct power supply or a serial voltage regulator), or the power input is wrong for your system (use the correct power supply or a serial adapter). In some cases, the servo drive hardware itself may be damaged, requiring you to send the drive back to the distributors or contact Delta.
