Function: Enter the maximum permissible current when using AC brake
to avoid overheating of motor windings. 100
％
equals motor
current set in C01.24.
C02.17 Function Description Range Unit Default Setting
Over-voltage Control 0~2 0
Option: [0] Disabled, The OVC is not active/required;
[2] Enabled, OVC is running;
Function: OVC is used to consume surplus energy by increasing the
output frequency. Select whether to enable OVC, which reduces
the risk of drive trip due to over voltage on the DC link caused
by generative power from load.
Attention: The OVC is not active/required if resistor brake has been
chosen in C02.01 (Brake Function).
C02.20 Function Description Range Unit Default Setting
Release Brake Current 0.00~100.0 A 0.00
Function: Set motor current at which mechanical brake is released. The
relay acts when motor speed is greater than settings in this
parameter.
Attention: If start delay time has passed, and motor current is below
Release brake current, frequency converter trips.
C02.22 Function Description Range Unit Default Setting
Activate Brake Speed 0.0~400.0 Hz 0.0
Function: The mechanical brake is activated when motor speed is less
than Activate Brake Speed.
Description of Choice: This feature occurs in the following situations:
● A start command is removed;
● A stop command is activated;
● Quick-stop is activated (Q-stop function is used);
C02.2* Mechanical Brake
For hoisting applications an electro-magnetic brake is required, brake
signal can be sent via the relay. The brake activates if f requency converter
trips or a coast command is given. Furthermore, it activates when the motor
speed is ramped down below the speed set in C02.22, Activate Brake Speed.
