actual position. This move may occur more rapidly than the user would like. To have a slower and safer initial startup,
the “Velocity Limit Starting” is used. It is only valid from the “Analog Position Mode Enable” until the position is reached.
The acceleration is limited by “Analog Accel/Decel Limit”.
Define Home Position
The Home Position value is used by the drive to set the actual position to this value after the “Home” input is activated.
A “Home” input is defined during the teach function
• Distance units (revs) has a range of -214748.3647 to [phone]
Analog Deadband
• Provides a deadband around the current position to filter out noise and prevent the motor from following the noise
signal
• Range: Volts 0 – 10.000
Following Error Limit
• Defines maximum position error between commanded position and the actual motor position.
• Drive will generate fault if following error is exceeded
Mode Selection
Once the analog position settings have been entered you can keep “Analog Position mode” selected and the drive will
operate in the analog position mode. Or you can select another operating mode such as Velocity and the drive will
operate in velocity mode until analog position mode is enabled via an input. The analog position settings window will
disappear but the values entered will still be set in the drive.
Analog Input Setup
Analog Input is used for Analog Velocity, Analog Torque and Analog Position.
Both Analog Velocity and Analog Torque use the settings of scale and offset while Analog Position uses a two point
definition. The two point definition allows for a teach method to define and calibrate the analog input settings to encoder
values by using an input function.

Bandwidth
• Bandwidth provides a lowpass filter on the analog input. Frequencies above this value will be ignored.
Analog Full Scale
• Range -10.000 to +10.000
• Defines the “Full Scale Velocity” or “Full Scale Torque” analog scaling.
