Response Characteristics
Response characteristics based on the customer’s
operating conditions will be confirmed on actual equipment
during the advanced testing stage, as deemed necessary.
The results will be presented as adjustment specifications

.
Representative characteristics are listed in Response
Characteristics (2-3).
*1 Repeatability of Positioning refers to a value at a certain temperature and a short period of time,
excluding drift.
*2 The selections of the applicable models may change in accordance with the customer’s operating
conditions.
Therefore, please fill-in the “Optical Scanner Drive Form” (2-4) and contact
our company before manufacturing the load devices or mounting parts.
2-3 Response Characteristics
By specifying the operating conditions and adjusting appropriately the driver according to the conditions,
the scanner system can provide an optimal performance for the focused characteristics. Therefore, the
response characteristics are different for adjustments emphasizing on accuracy and adjustments
emphasizing on response. In addition, if different conditions from adjusted operating conditions are
utilized, the operation of the drive may become unstable.
Our scanner system is appropriately adjusted to the customer’s operating conditions and is fundamentally
provided as a system. The explanation of the response characteristics of the rectangular and triangular
wave drives are on the following pages Using this as reference, please fill out the your usage conditions
in the “Optical Scanner Drive Form” (2-4) and submit this document to an agent or to our sales
representative.
