Product Description:
The FS1D140P00 is a stepper motor control unit manufactured by Sanyo Denki and distributed within the F SANMOTION Servo Amplifiers series. In an automation cell, it converts incoming pulse-train commands from a PLC into phased winding currents that advance a two-phase hybrid motor in precise increments, providing position control without encoder feedback. When paired with compatible SANMOTION motors, the driver supports compact axes for pick-and-place fixtures, indexing tables, and small dispensing pumps. Its pulse-based control method is suitable for applications where repeatable incremental movement is required without the added complexity of a closed-loop feedback device.
The motor resolution is selected through step modes that provide a full step of 0.72° per pulse or a half step of 0.36° per pulse, allowing the application to balance resolution and command bandwidth. Pulse inputs may reach 35 kilopulses per second, and operation within this limit helps prevent missed steps. An internal pull-up network provides an input impedance of 220 Ω, so the sending controller must supply adequate drive current. Operating logic is powered from a regulated bus of 24/36 VDC ±10%, accommodating both 24 V control cabinets and 36 V motion systems. Each optically isolated output transistor can sink up to 10 mA and withstand 40 V while off, allowing fault or ready signals to connect to standard digital inputs. Pulse duty must remain at 50% or less to preserve timing symmetry. The device is classified under Installation Category I and Protection Class III for use with low-energy SELV circuits.
The phase windings can draw a continuous current of 1.4 A, while the peak source path can supply a maximum of 3 A during acceleration. Dielectric integrity is verified by a withstand test of 1500 VAC for 1 minute, and the insulation resistance is 10 MΩ. The assembly weighs only 0.1 kg, reducing the mechanical load on its mounting surface. Cabinet airflow should circulate around the compact housing to prevent localized heat buildup during sustained operation. Proper conductor sizing and secure terminal connections help maintain stable current delivery to the motor windings. The low-voltage power arrangement also allows the driver to be integrated into compact control panels used for light industrial motion tasks.
