Stopping procedure
At the stop command, the operation frequency is decreased to the creep frequency set with parameter  and
the creep frequency is maintained for the creep time set with . While the creep frequency is maintained, the
brake release signal is put out through the braking signal output terminal to apply the brake.

Teaching function
Using this function, rough settings can be made automatically and also parameters ,  and 
can be set automatically.
After making settings with the teaching function, make fine adjustments if necessary.
[Teaching operation]
Set parameter  to  and enter an operation command to start teaching. (During teaching, a "T" appears
(blinks) on the left side of the frequency displayed.)
Parameter  (torque) is set, the brake release timing is calculated, and parameter  (release time) is
set based on the calculation result. At the stop of operation, parameters  (creep frequency) and 
(creep time) are set.
Note:Teaching should be performed under light-load conditions.
For the braking functions, the pre-excitation time is automatically determined by the inverter from motor-
related constants.
When the VFAS1-2037PL is used in combination with a Toshiba 4P-3.7kW-60Hz-200V standard motor, the
preliminary excitation time is approximately 0.1 to 0.2 seconds.
Depending on the motor used, the preliminary excitation time may be prolonged.
Motor constant setting
When using braking functions, set parameter  (automatic torque boost) to  (voltage vector control +
auto-tuning) or set motor-related parameters  to .
