Sets analog input terminals A1, A2, and A3 to supply the speed limit, torque reference, or torque compensation. If you set the same
function to A1 to A3 terminals with
H3-02, H3-10,
or
H3-06
, the drive will detect
oPE07 [Analog Input Selection Error]
.
Input Signal Polarity
The positive and negative torque references set the motor rotation direction. The direction of the Run command does
not set it. The positive and negative torque reference signals and the direction of the Run command have an effect on
the internal torque reference.

Note:
For Yaskawa motors, the forward run direction is counterclockwise direction when seen from the load shaft.
When you use analog inputs, you can get negative input values with these methods:
•
Apply negative voltage input signals.
•
Use positive voltage input signals and set the analog input bias to negative values.
•
Apply positive voltage input signals and use a digital input programmed for
Analog TorqueRef Polarity Invert [H1-
xx = 78]
.
When you use MEMOBUS/Modbus communication or a communication option card, set the positive or negative
signed torque reference.
When the level of the analog signal input is 0 V to 10 V or 4 mA to 20 mA, the torque reference is the forward
direction. To reverse the polarity of the torque reference, use one of these two methods:
•
Use a -10 V to +10 V voltage input
•
Set
H1-xx = 78 [MFDI Function Select = Analog TorqueRef Polarity Invert]
.
■
Speed Limit and Speed Limit Bias
The drive reads the speed limit setting from the input selected in
d5-03 [Speed Limit Selection]
. You can use
d5-05
[Speed Limit Bias]
to add a bias to this speed. Parameter
d5-08 [Uni-directional Speed Limit Bias]
sets how the drive
applies bias to the speed limit.
shows the relation between these settings:
