The oil pressure controls PID derivative time of the first group. The
smaller setup value is, the faster response will be. Responding too fast that
can easily lead to overshoot, cause system instability and running oscillation.
The greater setup value is, the slower response will be, responding too slow
that can easily lead to inefficient and product instability.
A3-05、A3-06、A3-07：PID of the first group oil pressure
The switching methods of PID groups refer to the servo pump commissioning steps of
chapter seven.
PID of the first group oil pressure corresponding to terminals combination: DI2（OFF）、DI3

It is the maximum reverse rotation when pressure relief, which corresponds to the
percentage setup of the manimum rotation speed. It is used to set the maximum reverse
rotation speed. The greater setup value is, the faster pressure relief will be.But excessive
noise cause pump reversal.The smaller setting value is, the slower pressure relief will be.
