1 BEFORE OPERATION
Thank you for your purchasing the STDF PD drive.
STDF PD is an all-in-one unit. For the high-speed and high-precision drive of a stepping motor,
STDF PD is a unique drive that adopts a new control scheme owing to an onboard
high-performance 32-bit MCU.
This manual describes handling, maintenance, repair, diagnosis and troubleshooting of the
STDF PD.
Before operating with STDF PD, thoroughly read this manual.
After reading the manual, keep the manual near the STDF PD so that any user can read it
whenever required.
1.1 Precautions
1.1.1 Put the Safety First
Before installation, operation and repairing the STDF PD, thoroughly read the manual and
fully understand the contents. Before operating the STDF PD please, understand the
mechanical characteristics of the STDF PD and related safety information and precautions.
This manual divides safety precautions into Attention and Warning.
Attention
If the user does not properly handle the product, the user may seriously or slightly be injured
and damages may occur in the machine.
Warning
If the user does not properly handle the product, a dangerous situation (such as an electric
shock) may occur resulting in deaths or serious injuries.
Although precaution is only an Attention, a serious result could be caused depending on the
situation.
Follow safety precautions.
5/24
1.1.2 Operation
Attention
If a protection function (alarm) occurs, firstly remove its cause and then release (alarm reset)
the protection function. If you operate continuously without removing its cause, the machine
may get damaged or the user may get injured.
Do not make Motor Free and make input signal to ON during operation. The motor will stop
and the stop current will become zero. The machine may get damaged or the user may get
injured.
Make all input signals OFF before supply input voltage to STDF PD. The machine may get
damaged or the user may get injured by motor operation.
All parameter values are set by default factory setting value. Change this value after reading
this manual thoroughly. Otherwise, the machine may get damaged or other kinds of accidents
may occur.
1.1.3 Check and Repair
Attention
Stop to supply power to the main circuit and wait for a while before checking or repairing the
STDF PD. Electricity remaining in the capacitor may cause danger.
Do not change cabling while power is being supplied. Otherwise, the user may get injured or
the product may get damaged.
Do not reconstruct the STDF PD. Otherwise, an electric shock may occur or the reconstructed
product can not get After-Service.

3 INSTALLATION
3.1 Precautions of installation
1. STDF PD is designed for indoor use only.
2. The ambient temperature of the room should be 0 °C ∼50 °C.
3. If the temperature of the product case is higher than 50 °C, radiate heat of the
outside to cool down.
4. Do not install STDF PD under direct rays, near magnetic or radioactive objects.
5. If you set more than 2 drives, you must set over 20 mm vertically and over 50 mm
horizontally as shown below.
Figure 3-1: Installation dimensions for 2 or more drives.

4 BRAKE OPERATION TIMING CHART
STDF PD controls Brake by Drive automatically.
Please refer to below Timing Chart when Brake is controlled by the upper controller other
than using STDF PD Brake control. Otherwise, Drive malfunctioning and loads can be fall
down.
Also, please do not operate Brake while motor operation to prevent damage.
Figure 4-1: Brake operation timing chart.
