LYD000A HITACHI control module

● When executing this instruction, the maximum frequency value is stored in the special internal output pulse output frequency (WRF072-WFR075), while the output pulse number is stored

In the special internal output (LYD000A).

● If the specified pulse output number is output pulse, do not execute this instruction.

If the output associated with the specified pulse output number is not set to pulse in-pulse output, then DER is set to "1" and no pulse output is generated.

● If the sum of the setting frequency of this instruction and the setting frequency of other pulse outputs exceeds 5kHz, DER is set to "1" and no pulse output is generated.

● If the maximum frequency value is less than the initial frequency value, DER set "1" and no pulse output.

If the maximum frequency and initial frequency are set to the same value, the pulse will output pulse i with the maximum period and i will not accelerate/decelerate.

● The maximum frequency value and initial frequency value are set to -values less than 10Hz, and the system will automatically change the specified value to 10Hz.

● If the total number of output pulses is small, the deceleration phase will begin when it does not rise to the maximum frequency. In this case, it will not follow the specified

Accelerate 1 deceleration time to accelerate 1 deceleration, but to accelerate 1 deceleration per pulse.

● For acceleration/deceleration time, set a value equal to or greater than (11 maximum frequency value + 1/ initial frequency value)x s if set -less than this value

The specified acceleration 1 deceleration time will not be set.

Acceleration and deceleration are performed in 10 steps, with at least one or more pulse outputs. So if you set a low initial frequency, at acceleration 1 deceleration time

The error will be larger.
