07KT93 ABB Central Processing Unit High-Speed Counter

07KT93 ABB Central Processing Unit with High-Speed Counter for 07 KT 93

Key Technical Specifications

• Brand: ABB
• Model: 07KT93
• Category: Central Processing Unit
• Basic unit: 07 KT 93
• Counter type: High-speed counter, independent of the user program
• Maximum counting frequency: 10 kHz
• Counter input: Terminal 02, also designated as E 62,00
• Counted edges: 0 to 1 transitions at terminal 02
• Counter read variable: EW 06,15
• Counter set variable: AW 06,15 with A 63,15 = 1
• Enable/disable variable: A 63,13 or A 63,14
• Zero-crossing message: Internal variable E 63,13; terminal 36 (A 62,00) when A 63,14 = 1
• Fast digital input delay: Less than 0.02 ms
• Dead time / reaction time: 0 to 1.5 ms

Counter Control and Signal Behavior

• Set A 63,14 = 0 to control counting with internal variable A 63,13.
• Set A 63,13 = 1 to enable counting; set A 63,13 = 0 to disable it.
• Set A 63,14 = 1 to enable counting through signal 1 at terminal 03 (E 62,01).
• With A 63,14 = 1, signal 0 at terminal 03 disables counting and A 63,13 has no effect.
• Set the counter to the value in AW 06,15 by setting A 63,15 = 1.
• If A 63,15 = 1 remains active over several cycles, the processor sets the counter at each program end.
• The counter keeps counting pulses at terminal 02 during the rest of the processing cycle.
• A zero-crossing message appears when the counter changes from -1 to 0.
• The zero-crossing message clears when you set the counter.
• Direct control of output A 62,00 from the user program is disabled when A 63,14 = 1.

Fast Digital Input Channels

• Terminal 02 (E 62,00) maps to internal variable E 63,14 with delay under 0.02 ms.
• Terminal 03 (E 62,01) maps to internal variable E 63,15 with delay under 0.02 ms.
• These fast inputs let the CPU capture short pulses that normal scan cycles would miss.
• Use them for position sensing, edge detection, and rapid event triggering.

Installation Guide

• Mount the 07KT93 in the 07 KT 93 basic unit according to ABB system drawings.
• Connect the counting signal to terminal 02 and the enable signal to terminal 03.
• Wire terminal 36 if you need the hardware zero-crossing output at A 62,00.
• Keep counter and fast input cables short and shielded to protect signal integrity.
• Separate these cables from motor and relay wiring to reduce electrical noise.
• Verify counter readings and zero-crossing messages in the user program after power-up.
• Confirm that A 63,14 and A 63,13 settings match your intended control method.

FAQ

• Q: What is the maximum counting frequency of the 07KT93 counter?
  A: The high-speed counter reaches a maximum frequency of 10 kHz.
• Q: Which terminal receives the counting pulses?
  A: Terminal 02, also designated as E 62,00, receives the 0 to 1 edge pulses.
• Q: How do I enable or disable the counting procedure?
  A: Use A 63,13 when A 63,14 = 0, or use signal 1 at terminal 03 when A 63,14 = 1.
• Q: How do I read the counter content?
  A: Read the internal variable EW 06,15 in the user program.
• Q: How do I set the counter value?
  A: Set A 63,15 = 1 to load the value from internal word variable AW 06,15.
• Q: What is the delay for fast digital inputs?
  A: The fast inputs on terminals 02 and 03 have a delay of less than 0.02 ms.
• Q: What is the dead time or reaction time?
  A: The dead time and reaction time may range from 0 to 1.5 ms.
