DAC Monitors J4-14 DAC MON1 J4-15 DAC MON2 The DAC Monitors are general-purpose analog monitor points. The output range is 0.5 to 4.5 V with a source impedance of 2.9 kW, which limits the short circuit to I/O RTN to 2 mA. Each DAC Monitor can be mapped by software to one of a number of internal variables. J4-13, 16, 23, 26 I/O RTN /O RTN is the ground reference for the DAC MON, Analog Command, Encoder output/inputs, and SFD BAT+. These pins are electrically shorted together inside the drive. Connect one of the I/O RTN pins to an earth ground point in the cabinet reserved for single point grounding of all returns (drives and supplies) to control common mode voltage. 6.7.6 Encoder Outputs/Inputs J4-19 CH A OUT/IN J4-20 CH A OUT/IN J4-21 CH B OUT/IN J4-22 CH B OUT/IN Outputs Channels A and B are RS-485 compliant differential I/O that can be configured as either inputs or outputs. Default is as outputs. When configured as outputs and with high resolution feedback such as the SFD device, Channels A and B provide position signals generated from the feedback device that emulate a quadrature encoder. The outputs are buffered by 5.0 V, 75LBC170 type RS-422 compatible line drivers. Recommended load current is ±20 mA, which corresponds to a line-to-line load resistance of 100 ?. These outputs can handle shorts to I/O RTN indefinitely without damage. The resolution of the Encoder Outputs (number of pulses per motor revolution), is set by S1 (rotary switch), as follows:1 User settable non-volatile PPR via the serial port. Possible PPR are: 128, 512, 1024, 2048, 4096, 8192, 16384, 32768, 125, 500, 1000, 2000, 2500, 5000, 10000, 20000 The maximum output line frequency is 2.5 MHz. Limit line frequency to below 1.25 MHz, which corresponds to quadrature count frequency below 5 MHz, for robust operation. NOTE The emulated encoder output is only available when using a high resolution feedback device such as the SFD feedback to the base unit or Encoder feedback to the option card. The emulated encoder outputs have no signals when there is only base unit 6-step feedback. Inputs Channels A and B can be configured as inputs by setting NV Parameter PosCmdSrc to AQUADB. With NV Parameter OpMode set to Position and PosCmdSrc to AQUADB, the motor shaft position command comes from the quadrature decode of channels A and B input scaled by the ratio of NV Parameters GearOut over GearIn. 

In Input mode, Channels A & B accept quadrature position commands. The command signals need to be differential quadrature signals. Channel A leading B generates a CW position command while Channel B leading A generates a CCW position command. The magnitude of the command position is set by GearIn and GearOut. The maximum input line frequency for reliable operation is 625 kHz, which corresponds to a maximum quadrature pulse rate of 2.5 MHz.
