Product Description:
The PRS-3737D functions as a Servo Drive board that Sanyo Denki created through its engineering developments for industrial automation applications. The built-in regenerative resistors integrated in this unit control excess energy output during braking operations. The device has been engineered to operate under operational shocks reaching 19.6 m/s².
The PRS-3737D servo drive enables the selection of two encoder resolution choices, which include 1000 PPR and 2500 PPR. The device operates effectively with optical incremental encoders that track positions with high precision. According to storage recommendations, the component should be maintained within -20°C to +65°C when resting. An LED diagnostic system can be found on the front panel because it shows real-time operational status. The feedback signals from the encoder get processed through onboard filtering, which also applies amplification at the same time. The PRS-3737D servo drive maintains performance stability at heights reaching 1000 meters while serving various industrial site needs. A sinusoidal PWM system based on IGBT allows the motor to handle efficient signal output. Readers can easily find alarm connections that enable simple fault detection. The control unit provides manual calibration features.
The PRS-3737D servo drive accepts power from 200 to 240 VAC of voltage. The control system in this device requires powering through single-phase 200-240 VAC. A dense configuration on the internal PCB enables stable signal pathways because of its design. The construction allows for modular insertion into multi-axis drive control equipment. This system functions under vibrations that reach 4.9 m/s² maximum. The logic components receive a 5V DC isolated power supply from the main power. A rotary switch is an integral part of the system for conducting manual fault testing operations. This device operates in humid environments with readings between 0 to 90% without forming condensation.
