Example:
When using Pr.03.11 and Pr.03.12 are used in life equipment as above figure. The timing
figure is shown as follows. The DC brake is used before start-up and after stop. It can have
high output torque at the beginning of start-up. The Brake Release Frequency (Pr.03.11) can
be set by the requirement. The Brake Engage Frequency (Pr.03.12) can be set by requirement
to be used when stopping near 0Hz to prevent vibration of counterforce for smooth operation.

『
Function of Output Frequency
Control Multi-output terminal ON/OFF
』
: When output frequency is greater than
Pr.03.11(Brake Release Frequency),
this multi-function output terminal is conducted
；
When output frequency is less than Pr.03.11 (Brake Release Frequency),
this multi-
function output terminal is open circuit.
Please note that when you select this function,
Pr.03.11 MUST be greater than Pr.03.12, otherwise the multi-function output terminal is
always in open circuit condition.
