Brake mon. input:
For self-monitoring of the brake micro-switches when Encabit-Plus
module is not used especially for geared machines with traction sheave or shaft brake. A
normally close contact (N.C.) of each brake microswitch (closed when the brake coil is
de-energized) must be connected to the programmable input PIN in serial. This function
is active only when parameter “11.6 Brake mon” is enabled. Refer to “ADrive A3 Test
Instructions” for further information.
11.5 – Output limit frequency
(Flim: 1 – 100 Hz)
The limit value of driver output frequency when the parameter
11.4
is set to “Check
Fout<Flim” control.
11.6 – Brake release monitoring
(Enabled / Disabled)
The control of brake release monitoring function.
The microswitches of the brakes can be connected either to input PI1 on ENCABIT-Plus
module or programmable input PIN on ADrive as described in the section
13.2.5
. Refer to
“ADrive A3 Test Instructions” for further information.
11.7 – PTC temperature monitoring
(Enabled / Disabled)
The control of PTC temperature monitoring function.
Motor PTC & brake resistor thermostat can be connected to PI2 input on ENCABIT-Plus
module (usually when the inverter and the lift controller are located in separate places). In order
to enable this function, the driver must be equipped with ENCABIT-Plus module and the
connection must be made as described in the section
13.2.6
.
11.8 – Over-gain detection function
(S_OGD Func: Enabled / Disabled)
The control of anti-rollback over gain detection function.
This function can only be enabled when the parameter
3.5
Anti-rollback position
controller is activated.
If too high values are entered for anti-rollback position controller gains
3.6
and
3.7
, the
motor can go into oscillation at start-up. This case can lead noisy and instable start-up. This
function is used to detect the over-gain. When an over-gain is detected, the inverter gives the
following warning:
Then the inverter stops the OGD function and drives the motor with acceleration ramp.
It is suggested to keep this function enabled.
