Mode #03 Example #2: Reverse-Acting PID
• P7�29 must be less than P7�30�
• 30kg is the setpoint (same as example #1)�
Set the following parameters:
• P4�03 = 5 (AI1 as PID Feedback Signal)
• P7�00 = 1: (PID Reverse Local/Remote), 3: (PID Reverse
Remote Only), or 5: (PID Reverse Local Only)
• P7�29 = 110% [Sleep Reference 33kg = (110%)·(30kg)]
• P7�30 = 120% [Wake-up Reference 36kg = (120%)·(30kg)]
• Case #1: If Feedback < 33kg, frequency decreases
• Case #2: If Feedback > 36kg, frequency increases
Zone PID Physical Quantity
Sleep Zone
When greater that 36kg,
the GS4 drive goes to sleep
Transition Zone
When between 33kg~36kg,
the GS4 drive remains in its
previous status
Wake-up Zone
When less than 33kg;
in this case 30kg is the
setpoint�
