5.6 Dwell Operation
The dwell operation is used to maintain torque during the application and release of the
mechanical brakes on lift-type loads. Inverter dwell operation is based on the Acc/Dec dwell
frequency and the dwell time set by the user. The following points also affect dwell operation.
•
Acceleration Dwell Operation
: When an operation command runs, acceleration continues
until the acceleration dwell frequency and constant speed is reached within the acceleration
dwell operation time (Acc Dwell Time). After the Acc Dwell Time has passed, acceleration is
carried out based on the acceleration time and the operation speed that was originally set.
•
Deceleration Dwell Operation
: When a stop command is run, deceleration continues until
the deceleration dwell frequency and constant speed are reached within the deceleration
dwell operation time (Dec Dwell Freq). After the set time has passed, deceleration is carried
out based on the deceleration time that was originally set, then the operation stops.
