Note:
1. When the PLSR instruction is used in a program, the outputs used in the PLSR instruction
cannot be used in the PLSY instruction or PWM instruction.
2. When several pulse output instructions (PLSY, PWM, PLSR) use Y0 as the pulse output in the
same program, and if they are executed simultaneously in the same scan cycle, the ELC will
perform the instruction with the fewest step numbers.
3. The maximum output pulse frequency is the same as that of the PLSY instruction. After
M1133~M1135 and D1133 are set in ELC-PA/PC/PH series models, the maximum pulse
output frequency of Y0 is 50KHz.
Functions in ELC-PV series:
1. Relevant devices for the ELC-PV series:
X0
PLSR K1000 D10 K3000 Y0
2. The range of the pulse rate for this instruction is 10 ~ 200,000Hz. If the values of maximum
speed and acceleration/deceleration time exceeds the range, the ELC will operate with the
default value that is within the range.

3. The acceleration/deceleration of the PV series is based on the number of pulses. If the output
cannot reach the maximum acceleration frequency within the acceleration/deceleration time,
the instruction will automatically adjust the acceleration/deceleration time and the maximum
