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) 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 injury or fire.
(3) For the driver's power supply, use a DC power supply with reinforced insulation
on its primary and secondary sides.
Failure to do so may cause electric shock.
(4) This product is designed for use within machinery, so it should be installed
within an enclosure.
Failure to do so may cause injury.
(5) Do not transport, move, install the product, perform connections or inspections
when the power is on.
Doing so may cause electric shock, injury or fire.
(6) Only qualified personnel are allowed to transport, move, install the product,
perform connections or inspections.
Failure to do so may cause injury or fire.
(7) Do not touch the driver during operation or immediately after stopping.
Doing so may cause burn on the skin due to overheating of the driver.
(8) Ensure to use this product according to the method specified
in the Instructions Manual and within the specifications.
(9) 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.
(10)
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.

HOLD CURRENT changes relative to DRIVE CURRENT setting.
The ratio of HOLD CURRENT [100%] represents the same as the setting for
DRIVE CURRENT.
●
The effective range of the HOLD I.SEL switch varies according to the setting
of the DRIVE I.SEL switch.
●HOLD電流の割合を高くすると、停止時のモータ発熱が高くなります。
The greater the ratio of HOLD CURRENT grows, the more heat the motor
generates when is on holding-state.

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,
set the SPI SEL switch to [OFF(2P)].
●When the motor is operated with the pulse signal and direction signal
input, set the SPI SEL switch 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 .
As for input timing, refer to "10-2. (2)Drive pulse input（CW, CCW)"
