H4: Multi-Function Analog Output Terminals - YASKAWA V1000 Series Technical Manual

5.7 H: Terminal Functions
Setting the analog input to PID set point allows the analog input level to be the PID set point as a percentage of maximum output frequency (E1-04). The
frequency reference selected in parameter b1-01 no long becomes the PID set point.
Setting E: Motor Temperature
In addition to or in place of the oL1 (motor overload) fault of the drive, it is possible to use a PTC (Positive Temperature Coefficient) thermistor for motor
insulation protection. The PTC thermistors are built into the windings of some motors and will vary their resistance based on temperature. For details,
see .
Setting F: Not Used
Use this setting when the terminal is not used or when using the terminal as a through-put.
Setting 10: Forward Torque Limit
Setting 11: Reverse Torque Limit
Setting 12: Regeneration Torque Limit
Torque limit can be independently set by the analog input programmed for the proper motoring condition (quadrants 1, 2, 3, and 4) as a percentage of
motor rated torque. Available only when using Open Loop Vector Control.
Setting 15: Torque Limit
Torque limit can be set by the analog input programmed torque limit for forward and reverse motoring conditions (quadrants 1 and 3) as a percentage of
motor rated torque. This function is available only when using Open Loop Vector Control.
Setting 16: Differential PID Feedback

An analog input filter can be used to prevent erratic drive control when a "noisy" analog reference is used. Parameter H3-12 sets the time constant for a
first order filter that will be applied to both the A1, A2, and A3 analog inputs. The drive operation becomes more stable the longer the time programmed,
but it becomes less responsive to rapidly changing analog signals.

H4: Multi-Function Analog Output Terminals

u
These parameters assign an output to multi-function analog output terminal AM for monitoring a specific aspect of drive performance.

n
Select the data to be output through multi-function analog output terminal AM. Set the desired monitor parameter to the digits available in Uo-oo.
Example: Enter "103" for U1-03.
