GVD Series

GVD Series

Product catalog summary
Specifications:
The document outlines the specifications for the GVD0/GVDW0 model of galvanometer optical scanner drivers. Key specifications include:
  • Power Supply Voltage: ± 15V or ± 24V
  • Max. Operating Current: 2.5A RMS
  • Peak Current: 10A (may be limited by scanner type and power supply voltage)
  • Command Signal Input Voltage Range: ± 3V, ± 5V, or ± 10V (differential)
  • Input Impedance: 20kΩ (differential input)
  • Monitor Output Position Output: ± 1.5V, ± 2.5V, or ± 5V
  • Operating Temperature Range: 0℃ to +50℃
  • Dimensions: 93 x 57.5 x 31 mm
  • Weight: Approximately 60g (including heat sink)
Functions and Protection:
  • Input Signal: Servo ON
  • Output Signal: Ready
  • Protection Features: Overheating, over-positioning, over-current, and sensor error
Control Systems:
The GVD series offers two control systems: P Control and PI Control.
  • P Control: Outputs a signal proportional to the error between the command signal and position feedback. It provides fast response and stabilization but may result in position errors due to distortion or friction.
  • PI Control: Outputs a time-integrated signal of the error, maintaining a stationary state with minimal position error, regardless of distortion or friction. It offers high position repeatability.
Selection between P Control and PI Control should be based on the application needs: P Control for high-speed stabilization and PI Control for high position repeatability.

Please read the following description of the systems and select one according to your application. This control will output the signal proportional to the error which is obtained by comparing position feedback and command signal. The scanner responds fast and stabilizes position quickly because servo closed loop band becomes high by not integrate the time. In case of distortion or friction, a position error may occur against the command. 指令信号と位置フィードバック信号を比較しエラーに比例した信号を出力し ます。時間積分しないためサーボクローズドループ帯域が高くなります。従っ てスキャナは高速に応答し、速やかに整定します。歪みやフリクションが生 じた場合、指令に対して位置誤差が発生します。 This control will output the time-integrate
