energy, aeronautics-related equipment, automobiles, ships, medical appliances
directly handling the human body and equipment that might seriously affect
properties.
(2) Do not use or keep the product in explosive or corrosive environments,
in the presence of flammable gases, locations subjected to splashing water,
fine particles, soot, steam, or exposed to radiation or direct sunshine.
Doing so may cause electric shock, injury or fire.
(3) Do not transport, move, install the product, perform connections or inspections
when the power is on.
Doing so may cause electric shock.
(4) This product is for a devices inclusion.
Please establish it into enclosure without fail.
(5) Please do not touch the driver during after operation for a while,
may cause burn on the skin due to overheating of the driver.
(6) Ensure to use this product according to the method specified
in the Instructions Manual and within the specifications.
(7) 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.
(8) 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.

４－２．Setting HOLD CURRENT ADJUSTMENT trimmer
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%.

Ratio of HOLD CURRENT (typical)
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. 0.05A or less.

Erroneous setting may cause breakage of
the machine or injury due to unexpected
rotation of motor.
Ensure correct setting.
2-pulse input method/1-pulse input method are
set up by the SPI SEL switch.
Set this switch with power OFF.
The switch is factory-set to 2-pulse input method[OFF(2P)].
(1) Turn power [OFF].
(2) Set the SPI SEL [2P/1P] switch.
●When the motor is operated with two pulse signal inputs of CW and CCW,
switch the SPI SEL to [OFF(2P)].
●When the motor is operated with the pulse signal and direction signal
input, switch SPI SEL to [ON(1P)].
● In the case that 1-pulse input method is selected, the CCW terminal becomes
direction signal input designating the direction of the motor rotation.
Drive pulse set to the CW terminal(CW+,CW-).
● The input timing is same with 2-pulse input method and 1-pulse input method .
