24: Oil pressure control output (NC)
In the oil pressure control mode, modication of these parameters is retentive at power failure. The parameters
will restore to the values automatically set when the servo drive is powered on again. After the oil pressure control
mode is switched over to the non-oil pressure control mode, the parameters are restored to the values before the
system is switched over to the oil pressure control mode.
4.3.4 Oil Pressure PID Response Control
■
Oil Pressure PID Group Determined by DI
The IS580 provides four groups of PID parameters, one of which is selected based on the state combinations of
DI2 with function 48# and DI3 with function 49#. The following table describes the relationship between PID group
selection and states of the DIs.
The following table describes how to set the DI states to select the PID group.
DI3 with Function 49# DI2 with Function 48# PID Group
0 0 PID group 1: A3-05, A3-06, and A3-07
0 1 PID group 2: A3-11, A3-12, and A3-13
1 0 PID group 3: A3-14, A3-15, and A3-16
1 1 PID group 4: A3-17, A3-18, and A3-19
To achieve a faster system response, increase the proportional gain Kp and derivative time Kd and decrease the
integral time Ki. Be aware that quicker response may lead to overshoot and system oscillation.
Decreasing the proportional gain Kp and derivative time Kd and increasing the integral time will slow the system
response. Be aware that too slow response will reduce system efciency and product stability.
