◆The input
filter time constant is used for digital filter of the input signal, in order to
avoid interference of the system.
◆The bigger the filter time constant, the higher the immunity level and the longer the
response time is. On the contrary, the smaller the time constant, the shorter the
response time and the lower the immunity level is. If the best setting is not clear, you
can adjust setting value according to the status of control stability and response delay
time.
P4.16 PG Pulse Range
Range: 1～9999【1024】
Note:
◆The setting value of P4.16 (Number of pulses per revolution of PG) is determined by
the characteristic parameters of PG.
P4.17 AO1 function definition
Range: 0～11【0】
P4.18 AO2 function definition
Range: 0～11【1】
P4.19 DO function definition
Range: 0～11【11】
0: Output frequency before
compensation (0~Max frequency)
1: Output current (0~2 times of ac drive’s
rated current)
2: Output voltage (0~Max Voltage) 3: PID feed (0~10V)
4: PID feedback (0~10V) 5: Adjust signals (5V)
6: Output torque (0~2 times of motor’s
rated torque)
7: Output power (0~2 times of Ac drive’s
rated power)
8: Bus voltage (0~1000V) 9: AI1 (0~10V)
10: AI2 (0-10V/0~20mA) 11: Output frequency after compensation
(0~maximum frequency)
12~14: Reserved 15: NULL
Note:
◆ The ac drive has two analog outputs（3004GB and the below models as one signal）.
The output can be voltage or current. The full range of voltage is DC 10V and the
current is 20mA. You can select what to output, and adjust the range according to
your actual need.
◆ The ac drive model of 3004GB and the below models have only one analog
channel (AO1).The corresponding P4.18, P4.21and P4.23 all cannot be set.
P4.20 AO1 output range selection
Range: 0,1【0】
P4.21 AO2 output range selection
Range: 0,1【0】
0: 0~10V / 0~20mA 1: 2~10V / 4~20mA
P4.22 Gain of AO1
Range: 1~200%【100%】
P4.23 Gain of AO2
Range: 1~200%【100%】
