Command Source Of Speed Control Mode - Delta Electronics ASDA-A Series User Manual

Chapter 6 Control Modes of Operation

6-3-1 Command Source of Speed Control Mode

Speed command Source:
1. External analog signal: External analog voltage input, -10V to +10V
2. Internal parameter: P1-09 to P1-11
Speed DI signal of CN1
Command
SPD1
S1 0
S2 0
S3 1
S4 1
State of SPD0~1:
0: indicates OFF (Normally Open)
1: indicates ON (Normally Closed)
When SPD0=SPD1=0 (OFF), if the control mode of operation is Sz, then the command is 0. Therefore,
if users do not use analog voltage as speed command, users can choose Sz mode to operation speed
control to avoid the zero point drift problem of analog voltage. If the control mode of operation is S, then
the command is the analog voltage between V-REF and GND. The setting range of the input voltage is
from -10V to +10V and the corresponding rotation speed is adjustable (see parameter P1-40).
When one of SPD0 and SPD1 is not 0 (OFF), the speed command is internal parameter. The
command is valid (enabled) after SPD0~1 is changed and it doesn't need that CTRG should be
triggered.
The speed command that is described in this section not only can be taken as speed command in speed
control mode (S or Sz mode) but also can be the speed limit input command in torque control mode (T or Tz
mode).
