8.2.5 Controls
This instrument controls with open loop control or PID control (closed loop control).
(1) Open loop control
In a deviation between the motor speed measured value and set value is larger than the H-SIO-A
control range set value, or the H-SIO-A open/closed loop control transfer is “1: Open loop control,”
the instrument is in open loop control, thereby outputting a constant control output value
corresponding to the motor speed set value.
H-SIO-A control range:
The motor speed measured value to perform PID control (closed loop control) and the deviation
from the motor speed set value are set.
Setting rage: 0.00 to 50.00 %
Example 1: When control output value is 10 V DC at maximum motor speed of 1000 mm/min.
Control output:
Voltage output 0 to 10 V DC
Output scale high: 1000
Display scale high: 1000
Output scale low: 0
Display scale low: 0
Example 2: When control output value is 9 V DC at maximum motor speed of 1000 mm/min
Control output:
Voltage output 0 to 10 V DC
Output scale high:
1111 *
Display scale high: 1000
Output scale low:
0
Display scale low: 0
Output limiter high:
