31 Counter module XN-322-1CNT-8DIO31.6 Memory layout266 XN300 slice modules 06/16 MN050002 EN www.eaton.com0x30F1 4 Pause time, measured by counting internal clock signals in this 32-bit counter register.The register contains the number of pulses, from an internal time reference, counted between the last two counter valueincrements (rising edges on signal A). The register value with the counted pulses is refreshed with a rising edge on A orwhen the maximum value is reached. Accordingly, this register makes it possible to represent count pulses per time unit forthe frequency or speed measurement. The direction (sign) is determined based on the evaluation of the signal sequencewhen in AB quadrature mode.0x30F2 2 Counter value (16-bite incremental encoder counter value)The counter resolves edges into numbers of pulses and directions. X1, X2 and X4 encoding are available.0x30F3 2 Stored counter value (stored 16-bit incremental encoder counter value)This register contains the counter value stored by a latch pulse. The input that triggers this action must be configured accord-ingly.0x30F4 1 Incremental encoder status register Bit 0-3 reservedBit 4 Zero positionBit 5 reservedBit 6(State +24V X4)24 VDC OK on supply to outputsBit 7(State +24V X1/X2)24 VDC OK on supply to incremental encoder0x40F2(WRITE)4 Max. waiting time value (count range for the waiting time register (max. 31-bit))This register uses the register width to define the maximum value for the waiting time. When the maximum value is reached,a motor stop is identified, for example.0x40F3 1 Cycle prescaler for determining the waiting timePrescaler periods = Cycle [Hz] * Measuring time [sec]0x40F4(READ)1 Pulse frequency (System Clock)Pulse frequency in MHz0x40F5 2 Counter value as acyclical access (16-bit incremental encoder counter value)0x40F6 1 Incremental encoder configurationregisterBit 0 …1 reservedBit 2 Inverted logic for R zero-position evaluationBit 3 Inverted logic for B phase evaluationBit 4 …5 Bit5 Bit4Signal analysis0 0 off0 1 single encoding1 0 double encoding1 1 four sample encodingBit 6 … 7 reservedCAN object Size(byte)Description
