Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: Set the phase relation of output pulses between phase A and phase B and polarity of Z pulses when the rotating direction of the motor remains unchanged. bit0=0 : A is ahead of B when the motor rotates forward bit0=1 : B is ahead of A when the motor rotates forward bit1=0 : Z pulses are of high level, i.e. when output at the Z pulse port turns from low level to high level, it means the encoder reaches the origin of a single turn. bit1=1 : Z pulses are of low level, i.e. when output at the Z pulse port turns from high level to low level, it means the encoder reaches the origin of a single turn.
Parameter functions: Expand the width of Z pulses. When the upper computer cannot capture relatively narrow Z pulses, the width of the Z pulses may be expanded. As the width of Z pulses will reduce as the motor speed increases, the width of Z pulses may be adjusted based on the actual conditions for better accommodation to different upper computers. When it is set to 0, it means the output of Z pulses is the original width of the encoder’s Z signal. Parameter functions: Select a source for frequency division output. P0-24=0 : The source of pulse output is the encoder feedback. P0-24=1 : The source of pulse output is command pulses received by the driver (without electronic gear calculation).
At this time, parameters, P0-20, P0-21 and P0-22 are invalid. Signals acquired from the PULSE channel are output through PB+ and PB-; signals acquired from the SIGN channel are output through PA+ and PA-. P0-24=2 : The source of pulse output is speed commands; the pulse frequency is determined based on the P2-16 setting. P0-24=3 : The source of pulse output is the external encoder feedback.
