YASKAWA ELECTRIC
SIEP C710617 19A YASKAWA AC Drive CR700 Technical Manual
Inputs the voltage signal of -10 V to 10 V. This setting enables positive and negative polarity signals. When this
setting is used as the frequency reference, the motor runs reverse when the Forward run command is input, or runs
forward when the reverse run signal is input, while the signal is a negative number due to the gain and bias
adjustment.
2 : 4 to 20 mA
Inputs the current signal of 4 mA to 20 mA. The signal is reset to 0% when it becomes a negative number due to
gain and bias adjustment.
3 : 0 to 20 mA
Inputs the current signal of 0 mA to 20 mA. The signal is reset to 0% when it becomes a negative number due to
gain and bias adjustment.
Note:
When
H3-09 = 0, 1
, set DIP switch S1 to the V side (voltage). When
H3-09 = 2, 3
, set DIP switch S1 to the I side (current). The default
setting is the I side (current).

Terminal A2 Gain
Setting
Sets the gain of the analog signal input to MFAI terminal A2.
100.0%
(-999.9 - +999.9%)
When 10 V (or 20 mA) is input, this parameter sets the reference quantity for the function set for terminal A2 as a
percentage.
Use this parameter and
H3-12 [Terminal A2 Bias Setting]
to adjust the characteristics of the analog input signal to
terminal A2.

Terminal A2 Bias
Setting
Sets the bias of the analog signal input to MFAI terminal A2.
0.0%
(-999.9 - +999.9%)
When 0 V (4 mA or 0 mA) is input, this parameter sets the bias for the function set for terminal A2 as a
percentage.
Use this parameter and
H3-11 [Terminal A2 Gain Setting]
to adjust the characteristics of the analog input signal to
terminal A2.

Analog Input
FilterTime Constant
Sets the time constant to apply a primary delay filter to the MFAI terminal.
0.03 s
(0.00 - 2.00 s)
Apply the primary delay filter to the analog input to enable an analog input signal without the use of high-
frequency noise components. An analog input filter prevents irregular drive control. Drive operation becomes
more stable as the programmed time becomes longer, but it also becomes less responsive to quickly changing
analog signals.
