Chapter 4 Explanation of Functions (Control block diagram) ATR terminal Torque bias Torque limit Torque command input Torque command (Current control command) Speed control (P control) Speed limit Detected speed Speed monitoring If the detected speed exceeds the speed limit, the motor speed is controlled in proportional (P) control mode. 4.3.6 Pulse train position control mode - To use this function, specify "05" (V2) for V/F characteristic curve selection, 1st motor (A044) and "01" (pulse train position control mode) for the control pulse setting (P012). - You can choose the input source of pulse train command pulse train mode setting (P013). Item Function code Data or range of data Description Control pulse setting P012 01 Pulse train position control mode 00 MD0: 90°-phase-shift pulse train Pulse train mode setting (*2) P013 01 MD1: Forward/reverse operation command with pulse train 02 MD2: Forward-operation pulse train with reverse-operation pulse train Home search completion 0. to 9999. / 1000 P017 range setting (100000) Equivalent to encoder quadruplex Home search completion delay time setting P018 0.00 to 9.99 (s) Electronic gear set position 00 FB : Feed back side P019 selection 01 REF : Controller side Electronic gear ratio numerator setting P020 1. to 9999. Electronic gear ratio denominator setting P021 1. – 9999. Feed-forward gain setting P022 0.00 to 99.99 / 100.0 to 655.3 Position loop gain setting P023 0.00 to 99.99 / 100.0 (rad/s) Position bias setting P024 -204 (-2048) / -999. to 2048. Terminal function C001 to C008 47 PCLR: Clearance of position deviation data 48 STAT: Pulse train position command input enable *1 In pulse train position control mode, the frequency value of a frequency command is calculated as follows: 6.4×P×Kv Frequency command (Hz) = × ENC ⊿P 255 P: Number of poles of the motor Kv: Position loop gain ENC: Encoder pulse count ⊿P: Position deviation In position control mode, the setting for the acceleration and deceleration time is invalid. (The LAD cancellation function operates automatically to ignore acceleration and deceleration patterns.) When the position loop gain is larger, the acceleration/deceleration time is shorter. 4 - 100
