2. Curve 1 is defined with [E0.16] − [E0.19], and curve 2 is defined with
[E0.20] − [E0.23]. Either of them can independently realize positive and
negative actions, as shown in fig. 7-42 "Output frequency characteristics
curves" on page 118 .

● Analog input A being 100 % corresponds to 10 V or 20 mA, and pulse
frequency P being 100 % corresponds to the maximum input pulse fre‐
quency defined with [E0.15].
● Parameter [E0.13] is used to select output frequency characteristic
curves for VR1, VR2, +I and PULSE frequency reference channels, as
shown in fig. 7-43 "Reference frequency curve selection" on page 118 .

● Parameter [E0.14] is used to define the analog channel filter time con‐
stant for processing of input signals. Longer filter time means stronger
anti-interference capability and slower response; shorter filtering time
means weaker anti-interference capability and faster response.
● Parameter [E0.09] is used to select the source of analog reference fre‐
quency. VR2 and +I inputs are active if [E0.09]=6.
● If [E0.09]=6 and the voltage range of VR1 analog input is -10 V to 0 V to
+10 V, direction information exists. In this case, the direction control with
