１－１．Safety Precautions
(1) This product is not designed or manufactured for application for equipment
requiring high level of reliability such as equipment related to nuclear
energy, aeronautics-related equipment, automobiles, ships, medical appliances
directly handling the human body and equipment that might seriously affect
properties.
(2) This product is for a devices inclusion.
Please establish it into enclosure without fail.
(3) Ensure to use this product according to the method specified
in the Instructions Manual and within the specifications.
(4) Depending on the operational conditions, the stepping motor may step out when
it is on holding-state or driving-state.
In particular, the load in transport may fall if the motor steps out on the
vertical drive (such as the Z-axis).
Start operation after test run for deliberate confirmation of operation.
(5) The stepping motor may attain high temperature, depending on the operational
conditions.
If the surface temperature exceeds 100℃, provide cooling measures to control
it to operate at 100℃ at the highest.
(6) Please do not touch the driver during after operation for a while,
may cause burn on the skin due to overheating of the driver.
(7) Provide fail-safe measures so that the entire system may operate in a safe
mode even in cases of the external power supply failure, disconnection of the
signal line, or any failure on the driver.

４－３．Setting HOLD CURRENT ADJUSTMENT trimmer R1
A high setting value may cause burn on the
skin due to overheating of the motor.
Do not select a high value beyond the
required.
HOLD CURRENT is set up with the HOLD I.ADJ trimmer.
This sets the ratio of HOLD CURRENT to DRIVE CURRENT.
The trimmer is factory-set to approx. 40%.

Scale of the trimmer
●
HOLD CURRENT changes relative to DRIVE CURRENT setting.
The ratio of HOLD CURRENT of 100% represents the same as the setting for
DRIVE CURRENT.
●The greater the ratio of HOLD CURRENT grows, the more heat the motor
generates when is on holding-state.
● When the trimmer is set minimum, HOLD CURRENT is approx. 10% or less of
DRIVE CURRENT.
