| D. Making Connections to the I/O Terminal Block (TB2) The Analog Interface Board's I/O Terminal block TB2 will accept a maximum of 16 gauge wire. A minimum of 22 gauge wire Is recommended. D. 1. Connecting the Analog Speed Control Inputs ABodineFPM adjustable speed control with an Analog Interface Board accepts both variable DC voltages and currents as speed control inputs. The Analog Interface Board has two speed control inputs, TB2-6 and TB2-7 (See Fig. 5). The speed control input is connected to terminal TB2-6 when the input signal isOto±5VDCor±(2 to 10) mA DC, and it is connected to terminal TB2-7 when the input signal is 0 to ±1OVDC or ±(4 to 20) mA DC. To Contrai the Motor Using an Adjustable DC Input Voltage (VJ: 1. Connect the signal common (low) side of the input voltage source to terminal TB2-2. 2. If the maximum value of the input voltage V|n is ±5V, connect the other (high) side of the input voltage source to I/O terminal TB2-6. If the maximum value of Vin is ±10V, connect the high side to TB2-7. To Control the Motor Using an Adjustable DC Input Current (IJ: 1. Connect the signal common (low) side of input current source to terminal TB2-2. 2. If the maximum value of the input current lin is ±10mA, connect the other (high) side of the input current source to TB2-6. If the maximum value of l(n is±20mA, connect the high side to TB2-7. |
