DEC
Analog gain value used in analog velocity modes. The gain value is used to establish the relationship
between the analog input and the motor speed in units of 0.25 rpm. For example, if the analog input is
scaled to 0 - 5 volt input and the gain is set to 2400, when 5 volts is read at the analog input the motor will
spin at 10 rps.
TIP: To set the analog velocity gain to the desired value, multiply the desired motor speed in rps by 240,
or the desired motor speed in rpm by 4.
NOTE: if you need to view or set this value on the drive’s control panel, refer to the following calculation:

This parameter sets the analog input gain that relates to motor torque when the drive is in analog torque
control mode. Analog torque gain value sets the commanded torque when the analog input is at the
configured full scale value (±10V).

0.000
A
DEC
The offset value of analog input 1 in volts. In some cases, even when host controls set the analog
command to 0V, the servo motor might still rotate slowly. This is caused by voltage bias from the analog
voltage supply. This can be adjusted by this offset value.
NOTE: if you need to view or set this value on the drive’s control panel, refer to the following calculation:
