Delta ASD-A2R-0421 Series - The Scaling of Analog Command; The Timing Diagram in Speed Mode

Chapter 6 Control Mode of Operation ASDA-A2R Series
6-20 Revision December, 2014
6.3.4 The Scaling of Analog Command
The motor speed command is controlled by the analog voltage deviation between V_REF
and VGND. Use parameter P1-40 to adjust the speed-control slope and its range.
Related parameter: Please refer to Chapter 8 for further information.
Parameter Abbr. Function Setting
P1-40 VCM
Maximum Speed of
Analog Speed
Command
Set P1-40 to 2000. If the input voltage is
10V, the speed command will be
2000r/min.
6.3.5 The Timing Diagram in Speed Mode
NOTE
1）OFF means the contact point is open while ON means the contact
point is close.
2
）When it is in Sz mode, the speed command S1 = 0; When it is in S
mode, the speed command S1 is the external analog voltage input.
3
）When the servo drive is On, please select the command according to
SPD0~SPD1 status.
The slope is determined by P1-40.
