Velocity feedback that outputs a voltage proportional to velocity. Similar to a small generator mounted to the motor shaft.
- These excellent velocity feedback devices were very popular in the past
- Encoders have supplanted tachometers because they can provide both velocity and position feedback in the same device
ADVANCED Motion Controls' Capabilities
- Some AxCent™ drives take ±60 VDC tachometer feedback to close the velocity loop
- DigiFlex® Performance™ drives take ±10 VDC tachometer feedback to close the velocity loop
