4.13 Advanced Drive Setup Adjustments
Setting 0: Current Detection
Setting 1: Speed Estimation
n b3-25: Speed Search Wait Time
Sets the wait time between Speed Search restarts. Increase the wait time if problems occur with overcurrent, overvoltage, or
if the SEr fault occurs.
No.
b3-25
n b3-27: Start Speed Search Select
Selects a condition to activate Speed Search Selection at Start (b3-01) or External Speed Search Command 1 or 2 from the
multi-function input.
No.
b3-27
Setting 0: Triggered when a Run Command Is Issued (Normal)
Setting 1: Triggered when an External Baseblock Is Released
n b3-29: Speed Search Induced Voltage Level
Lower this value in small increments if changes are necessary. Setting this value too low will prevent the drive from performing
Speed Search. There is normally no need to change this parameter from the default value.
No.
b3-29
n b5-01: PI Function Setting
Enables or disables the PI operation and selects the PI operation mode.
No.
b5-01
Setting 0: PI Disabled
Setting 1: Output Frequency = PI Output 1
The PI controller is enabled and the PI output builds the frequency reference.
Setting 3: Output Frequency = Frequency Reference + PI Output 1
The PI controller is enabled and the PI output is added to the frequency reference.
n b5-02: Proportional Gain Setting (P)
Sets the P gain applied to the PI input. Larger values will tend to reduce the error but may cause oscillations if set too high,
while lower values may allow too much offset between the setpoint and feedback.
No.
b5-02
n b5-03: Integral Time Setting (I)
Sets the time constant used to calculate the integral of the PI input. The shorter the integral time set to b5-03, the faster the
offset will be eliminated. If the integral time is set too short, however, overshoot or oscillation may occur. To turn off the
integral time, set b5-03 to 0.00.
No.
b5-03
n
b5-04: Integral Limit Setting
Sets the maximum output possible from the integral block as a percentage of the maximum frequency (E1-04).
