Trim Modes - Authority
In Trim Modes, it is typical to set Maximum voltage to 10 volts and Minimum
Voltage to 5 volts. 5 volts would then be the middle point of the scale where no
speed correction would be necessary. With this scaling 10 volts would provide the
maximum speed increase and 0 volts would provide the maximum speed
decrease, 5 volts would have no effect.
Trim Modes-Authority is the percentage of change to the set speed that the analog
input can make. For example, if you set the Maximum Volts for 10 volts and the
Minimum Volts for 5 volts and then set the Trim Modes-Authority for 10%, 10
volts would adjust the puller to run 10% faster than its set speed and 0 volts would
adjust to puller to run 10% slower than its set speed.
To set Trim Modes-Authority scaling:
1 Press the Puller section’s Analog Input, Trim Modes-Authority
window. A numeric pop-up keyboard appears.
2 Key in the Trim Modes - Authority. The value set here is the maximum effect
the analog input may have on the puller’s set speed.
3 Then press “Enter”. The pop-up keyboard is removed.
