FC 300 Design Guide 3. Introduction to FC 300 3.2.10. Scaling of References and Feedback References and feedback are scaled from analog and pulse inputs in the same way. The only difference is that a reference above or below the specified minimum and maximum “endpoints” (P1 and P2 in the graph below) are clamped, whereas a feedback above or below is not.

3. Introduction to FC 300 FC 300 Design Guide Thus, a reference endpoint of P1 = (0 V, 0 RPM) will not result in any dead band, but a reference endpoint of P1 = (1 V, 0 RPM), for example, will result in a -1 V to +1 V dead band in this case, provided that the end point P2 is placed in either quadrant 1 or quadrant 4.

A shorter time is allowed only if indicated on the nameplate for the specific unit. Leakage Current The ground leakage current from the FC 300 exceeds 3.5 mA. To ensure that the ground cable has a good mechanical connection to the ground connection (terminal 95), the cable cross-section must be at least 0.016 in.

(of the cycle time) Danfoss offers brake resistors with duty cycle of 5%, 10% and 40%. If a 10% duty cycle is applied, the brake resistors are able to absorb braking energy for 10% of the cycle time. The remaining 90% of the cycle time will be used on dissipating excess heat.
Page 48
The resistor brake circuit resistance selected should not be higher than that recom- mended by Danfoss. If a brake resistor with a higher ohmic value is selected, the 160% braking torque may not be achieved because there is a risk that the adjustable frequency drive cuts out for safety reasons.
FC 300 Design Guide 3. Introduction to FC 300 Placing the brake resistor externally offers the following advantages: The brake resistor can be selected on the basis of the application in question. The braking energy can be dissipated outside the control panel, i.e., where the energy can be utilized.

3. Introduction to FC 300 FC 300 Design Guide In hoisting/lowering applications, it must be possible to control an electro-mechanical brake. Step-by-step Description • To control the mechanical brake, any relay output or digital output (terminal 27 or 29) can be used. If necessary, use a suitable contactor.
3. Introduction to FC 300 3.8.2. Hoist Mechanical Brake The VLT Automation Drive FC 300 features a mechanical brake control specifically designed for hoisting applications. The hoist mechanical brake is activated by choice [6] in par. 1-72. The main difference compared to the regular mechanical brake control, where a relay function monitoring the output current is used, is that the hoist mechanical brake function has direct control over the brake relay.
3. Introduction to FC 300 FC 300 Design Guide To reduce the electrical noise from the wires between the brake resistor and the adjustable fre- quency drive, the wires must be twisted. For enhanced EMC performance, a metal shield can be used.
Page 53
FC 300 Design Guide 3. Introduction to FC 300 The load drives the motor (at constant output frequency from the adjustable frequency drive), i.e., the load generates energy. During deceleration ("ramp-down"), if the moment of inertia is high the friction is low and the ramp-down time is too short for the energy to be dissipated as a loss in the adjustable frequency drive, the motor and the installation.
