Position Mode; Position Command In Pt Mode - Delta ASDA-A3 Series User Manual

ASDA-A3 Operation Mode

6.2 Position mode

The servo drive provides two input modes for position control: external pulse (PT mode) and
internal register (PR mode). In PT mode, the servo drive receives the pulse command for
6
direction (motor runs forward or reverse). You can control the rotation angle of the motor with
the input pulse. The servo drive can receive pulse commands of up to 4 Mpps.
You can also accomplish position control using the internal register (PR mode) without the
external pulse command. The servo drive provides 100 command registers which you can set in
two ways. Set the 100 registers first before switching the drive to Servo On status. Then, you
can switch between commands with DI.POS0 - DI.POS6 of CN1 or directly set the register
values through communication.

6.2.1 Position command in PT mode

The PT Position command is the pulse input from the terminal block. There are three pulse
types and each type has positive and negative logic that you can set in P1.000. Refer to
Chapter 8 for more details.
