This happens when reference volt-age from the host controller or external circuit has a slight reference offset (in mV units). Ifthis offset is adjusted to 0 V, the motor will stop.When reference voltage from the hostcontroller or external circuit has an offsetOffsetOffset adjustmentOffset is correctedby the Servopack.ReferencevoltageReferencespeed orreference torqueReferencevoltageReference speedor reference torque2) The following two methods can be used to adjust the reference offset to 0 V.1) Automatic adjustment ofreference offset Reference offset is automatically adjusted to 0 V.2) Manual adjustment of referenceoffsetReference offset can be intentionally set to aspecified value.NOTE If a position control loop is formed in the host controller, do not use automatic adjustmentin 1. Always use manual adjustment in 2.3
