TECO A510s - Command Characteristic Selection of Master Frequency; Zero-Speed Operation Selection; Positive;Negative Analog Input as Main Frequency Reference Command

4-100
00- 28 Command characteristic selection of master frequency
Range
0: Positive characteristic (0-10V / 4-20mA = 0 -100%)
1: Negative / inverse characteristic (0-10V / 4~20mA = 100 - 0%)
00-28= 0: Positive reference curve, 0 – 10V / 4 – 20mA = 0 – 100% main frequency reference.
00-28= 1: Negative reference curve, 0 – 10V / 4 – 20mA = 100 – 0% main frequency reference.
Note: Selection applies to analog input AI1 and AI2.

00-29 Zero-speed operation selection
Range
0: Operation based on frequency command
1: Stop
2:
Operation based on lowest frequency
3: Zero-speed operation
Refer to figure 4.4.11 for zero-speed operation in sensor vector mode (SV / PMSV) (00-00=3 or 00-00=4).
