Sets the time the must wait between each Speed Search restart attempt.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the level that determines the direction of motor rotation.
Note: This parameter is available in models CIMR-A4A0930 and 4A1200.
V/f V/f w/PG
OLV/PM AOLV/PM
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.
0: Triggered when a Run command is issued (normal).
1: Triggered when an external baseblock is released.
V/f V/f w/PG
OLV/PM AOLV/PM
There is normally no need to change this parameter from the default value.
Performs Speed Search when the motor induced voltage exceeds the set level. If changes are
necessary, try lowering this value in small increments. If set too low, then the drive will not
perform Speed Search.
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
All Modes
Activates or deactivates the speed search at start in accordance with whether or not a Run
command was issued during an undervoltage (Uv) if operation during a momentary power loss
(L2-01 = 1 or 2), the speed search at start (b3-01 = 1), and coasting to a stop (b1-03 = 1) are
enabled.
0: Speed Search disabled
1: Speed Search enabled
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
All Modes
Used to set the on-delay and off-delay times for a digital timer output (H2-=12). The output
is triggered by a digital input programmed to H1-=18)
All Modes
Sets the length of the delay time for contact outputs to open or close for the related functions set
in H2-.
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
