Input Value Signal Source Settings Remarks
Speed Limit
Signal selected as
frequency reference

d5-03 = 1
The speed limit is taken from the input
selected as frequency reference source
in parameter b1-01 or b1-15.

The settings in C1-oo for accel/decel times and
in C2-oo for S-curves are applied to the speed
limit value.

Make sure the signal level settings for the input
terminal selected match the signal used. Refer to
H3: Multi-Function Analog Inputs on page
228 for details on adjusting analog input signals.

The H3-oo settings become effective for the
option board input terminals. Make sure the
signal level settings for the input terminal selected
match the signal used.

F6-06 = 1
Refer to the option card manual for
details about setting the torque
compensation value.
–
<1> Sets analog input terminals A1, A2, and A3 to supply the speed limit, torque reference, or torque compensation. Setting two analog inputs for the
same function will cause an oPE error.
Input Value Polarity
The direction of the input values described above depends on the polarity of the Run command and the input value.
Table 5.19 Torque Control Signal Polarity
Run Command Direction Input Value Polarity Input Value Direction
Forward
+ (positive) Forward direction
- (negative) Reverse direction
Reverse
+ (positive) Reverse direction
- (negative) Forward direction
Example:
• The internal torque reference will be positive (forward) with a Forward run command and a positive torque reference signal.
• The internal torque reference will be negative (reverse) with a Forward run command and a negative torque reference signal.
When using analog inputs, negative input values can be generated by:
• Applying negative voltage input signals.
• Using positive analog input signals while setting the analog input bias to negative values to make the input value negative.
When using MEMOBUS/Modbus communication or a communication option card, only positive input values can be set.
Independent of its input source, the polarity of the torque reference signal can be inverted using a digital input that is
programmed for H1-oo = 78. Use this function to input negative torque reference values when using MEMOBUS/Modbus
or a communication option card.
