Setting The Zero-Speed Operation Parameters - Omron SYSDRIVE 3G3FV User Manual

Basic Operation
VSG101043 and earlier software: Set values 0 to 3.
VSG101113 software: Set values 4 to 7.
Parameter F1-10 sets the PG speed deviation detection level as a percentage of the maximum output
frequency. Parameter F1-11 sets the length of time that the difference between the motor speed and
reference speed must exceed the PG speed deviation detection level in order to generate a PG speed
deviation fault (DEV).
Parameter Display name p y
number
F1-10 PG Deviate Level
F1-11 PG Deviate Time
Note A: Advanced
---: Not applicable.

5-4-2 Setting the Zero-speed Operation Parameters

With flux vector control, operation is possible even when the frequency reference is zero (below the
minimum output frequency). Parameter E1-09 sets the minimum output frequency and B1-05 sets the
operation method around this minimum frequency. These parameters cannot be changed during op-
eration.
H Selecting the Stopping Method (b1-03)
Parameter b1-03 sets the stopping method used when a stop command is input.
