D7: Offset Frequencies - Omron V1000 User Manual

5.4 d: Reference Settings
Setting 0: Lower Limit is Determined by d2-02 or Analog Input
The lower frequency reference limit is determined by the higher value of both, parameter d2-02 or an analog input that is
programmed for "Frequency Bias" (H3-02/10 = 0).
Note: If the external reference change over function (H1- = 2) used to switch between Up/Down function and analog input as reference
source, the analog value would become the lower reference limit when the Up/Down reference is active. Change d4-10 to 1 to make the
Up/Down function independent of the analog input value.
Setting 1: Lower Limit is Determined by Parameter d2-02
Only parameter d2-02 sets the lower frequency reference limit.
n d4-11: Bi-Directional Output Selection
Selects if the frequency reference or PID output value is converted into bi-directional internal frequency reference. Refer
also to the PID block diagram in
Note: When used in combination with PID control, the bi-directional output function can be enabled or disabled using a digital input (H1-
= 7F).
No.
d4-11
Setting 0: No Conversion
The frequency reference or PID output value is used as it is without being converted. The drive will operate in the direction
selected from 0 to 100% of the maximum output frequency.
Setting 1: Bi-Directional Output Conversion
When the frequency reference or PID output is below 50%, the drive reverses the selected direction. When it is above 50%
the drive works in the selected direction.
n
d4-12: Stop Position Gain
Sets the gain for adjusting the stopping accuracy when simple positioning is selected as the stopping method (b1-03 = 9).
No.
d4-12
Increase the value if the motor stops before the desired stop position is reached. Decrease it if the motor stops too late.
Refer to b1-03: Stopping Method Selection on page 105

d7-01 to d7-03: Offset Frequency 1 to 3
Three different offset values can be added to the frequency reference. They can be selected using digital inputs programmed
for Offset frequency 1, 2 and 3 (H1- = 44, 45, 46). The selected offset values are added if two or all three inputs are
closed at the same time.
Note: This function can be used to replace the "Trim Control" function (H1- = 1C/1D) of earlier OYMC drives.
No.
