4027 PID 1 PARAM SET
12 = 2- – The drive calculates the difference between setpoint 1 and feedback 1 as well as setpoint 2 and
ZONE MIN
feedback 2. The drive will control the zone (and select the set) which has a larger difference.
• A positive difference (a setpoint higher than the feedback) is always larger than a negative difference. This keeps
feedback values at or above the setpoint.
• Controller does not react to the situation of feedback above setpoint if another zone's feedback is closer to its
setpoint.
13 = 2- – The drive calculates the difference between setpoint 1 and feedback 1 as well as setpoint 2 and
ZONE MAX
feedback 2. The drive will control the zone (and select the set) which has a smaller difference.
• A negative difference (a setpoint lower than the feedback) is always smaller than a positive difference. This keeps
feedback values at or below the setpoint.
• Controller does not react to the situation of feedback below setpoint if another zone's feedback is closer to its
setpoint.
14 = 2- – The drive calculates the difference between setpoint 1 and feedback 1 as well as setpoint 2 and
ZONE AVE
feedback 2. In addition, it calculates the average of the deviations, and uses it to control zone 1. Therefore one
feedback is kept above its setpoint and another is kept as much below its setpoint.
