MH300
Not equal to 0.00 seconds: Enables the PID acceleration / deceleration command. For PID
acceleration and deceleration, when the PID target value changes, the command value
increment / decrement is executed according to this parameter.
Frequency Base Corresponding to 100.00% PID
Default: 0.00
Settings 0: PID control output 100.00%, corresponding to maximum operation
frequency (Pr.01-00)
1: PID control output 100.00%, corresponding to the input value of the
auxiliary frequency
Valid when you enable the auxiliary and master frequency functions.
When Pr.08-29 = 0, PID control output 100.00% corresponding to the maximum output frequency;
When Pr.08-29 = 1, PID control output 100.00% corresponding to the input value of the auxiliary
frequency. If the auxiliary frequency changes, the PID output frequency also changes.
Default: 1.00
Settings 0.0–5000.0 (when Pr.08-23 setting bit1 = 0)
0.00–500.00 (when Pr.08-23 setting bit1 = 1)
Default: 1.00
Settings 0.00–100.00 sec.
Default: 0.00
Settings 0.00–1.00 sec.
Source of PID Target Value
Default: 0
Settings 0: From frequency command (Pr.00-20, 00-30)
1: From Pr.08-66
2: From RS-485
3: From external analog (refer to Pr.03-00, 03-01)
4: From CANopen
6: From communication cards (CANopen card not included)
7: By the digital dial on the keypad
Selects the target value source for PID controller.
When Pr.08-65 = 0, the maximum operating frequency 01-00 is 60Hz, the error is 100%, and
Pr.08-01 = 1.00, the output frequency is '‟1” times of the Pr.01-00 maximum operating frequency,
therefore, the output frequency = 60 × 100% × 1 = 60 Hz.
Calculation formula:
Output frequency = Fmax (Pr.01-00) × error% ((PID reference value (Pr.00-20 / Pr.00-30) - PID
feedback (Pr.08-00)) × Pr.08-01.
