4. Press ENTER. Press either the up or down arrow key until the
following appears
5. Press ENTER. Use the up and down arrow keys to find Parameter
695, “Analog Vel Scale”.
6. Press SEL to select the numerical value.
7. Use the up and down arrow keys to change the numerical value.
8. To change the motor direction for a given analog voltage input,
press SEL to highlight the sign character.
9. Use the up and down arrow keys to change the sign.
Press ENTER.
In velocity mode with 0 volts at the auto analog reference input the
drive may still slowly rotate cw or ccw. To minimize this parameter
693, “Auto_Ref_Offset”, is provided. Values ranging from ±0.01% to
±100% can be entered. A plus value is used to offset in the cw
direction and a minus value is used to offset in the ccw direction.
Scaling of Manual Velocity
Analog Reference This section provides the information you need to scale a manual
velocity analog reference. Default scaling is 1000 rpm/10 volts.
To scale motor jog speed:
1. At the HIM, press ENTER. A message similar to the following
appears:
2. Press either the up or down arrow key until the following appears:
3. Press ENTER. Press either the up or down arrow key until the
