(2) Line speed control specifications: OPC-VG1-PG (LD)
This configuration is used when controlling the line speed of a winding device using
a PG installed on the line, rather than motor speed control.

Item Line speed control specifications
Card type (setting) OPC-VG1-PG (LD)
Control method
Vector control with speed sensor (induction motor, line speed control)
Line speed control is built into the standard configuration.
Control range
1 : 1500 (min. speed: base speed, 1.0 to 1,500 r/min. with 4P
conversion, using 1024P/R)
1 : 6 (constant torque region : constant output region)
Line speed
Vector control with
speed sensor
Speed control
accuracy
Analog setting: ±0.1% of max. speed
Digital setting: ±0.005% max. speed
PG interface functionality
With the PG interface expansion card installed and the LD setting
active:
Function code H53 = 2: Line speed detection enabled
Function code H53 = 3: High selector (line speed detection, motor
speed detection using built-in PG)
The encoder pulse count can be set using the o06 function code.
Pulse compensation Compensation can be performed using the o07 and 08 function codes.
Broken wire detection function None
Application functionality
The speed can be set for 15 speed stages in m/min. (function codes
C05 to C21).
Line speed detection (±max. speed/±10 V) output can be generated for
AO output.
Frequency division output
Output can be generated by dividing the frequency of standard built-in
PG interface input (line PG is not output).
