Description
magnetizing time. If parameter value is set to zero, the
function is disabled.
Defines the brake close speed. When frequency falls below
the set level during run, the brake is closed. The brake is re-
opened when the requirements set by parameters
4301...4305 are met.
Value in percent of the maximum frequency (in scalar
control) or the maximum speed (in vector control). If
parameter value is set to zero, the function is disabled. The
control mode is selected by parameter
MODE.
Selects the torque (in vector control) or current (in scalar
control) applied at brake release.
Value of parameter 4302 BRAKE OPEN LVL
Torque value (in vector control) or current value (in scalar
control) saved in parameter
used.
Useful in applications where initial torque is needed to
prevent unintended movement when the mechanical brake
is released.
Encoder connection.
For more information, see MTAC-01 pulse encoder interface
module user's manual (3AFE68591091 [English]).
States the number of encoder pulses per one revolution.
Enables the encoder.
Disabled
Enabled
Defines the operation of the drive if a failure is detected in
communication between the pulse encoder and the pulse
encoder interface module, or between the module and the
drive.
