Manual Tuning Procedure
If manual tuning of certain parameters is required, the following procedure
can be followed after all of the previous steps have been performed.
Parameters referenced in the following steps are located in the Modify
programming level. This level can be reached from the View level by
pressing the Up, Down and Left Arrow keys, simultaneously.
32.
Zero Speed Adjust
a) Remove all power from the drive.
b) Install a jumper between TB2-1 & 2 or leave the velocity
command wiring in place if the system offset adjust is being
performed.
c) Apply power, energize the contactor (M) and enable the drive.
d) Access the Offset parameter (210, Modify level) and increase or
decrease the value until the motor shaft does not rotate.
e) Perform step 36.
f) De-energize the Enable input, remove power and reconnect all
wiring, if applicable.
33.
Analog Velocity Gain
a) Apply power to the drive.
b) Energize the contactor (M), but Do Not Enable the drive.
c) Access the Analog Velocity Gain parameter (211, Modify level).
d) The drive will allow you to enter a value for the Analog Velocity
Gain.
The desired input velocity voltage to motor rpm scaling is
accomplished with the Analog Velocity Gain parameter (211).
The default setting is 500 rpm/volt. Use the following formula if
the maximum motor speed (rpm) and maximum velocity
command (volts) are known.

Enter the desired value followed by the Enter key.
e) Perform step 36.
f) Remove power and reconnect all wiring, if applicable.
