驅(qū)動控制器控制電機保持制動器。只要這個控制器制造商不提供功能。必須：使用外部設(shè)備。在這種情況下，連接外部制動電壓直接連接到電機上的制動器接頭BR+和BR-并且使用外部電路來切換它們。使用ADP電機時，溫度傳感器電纜可以：不連接到X6。應(yīng)使用750R電阻器連接在X6.1和X6.2之間。
對于ADP電機，溫度信號通過電機電纜僅用于控制器。
注：如果使用電機保持制動器，則必須連接外部24V三相電壓源。

即使使用更長的電機電源線，也會釋放（長電機電源電纜的電壓降可能為：通過增加電源電壓（高達(dá)DC+26.5V）進(jìn)行補償和/或在X6/3和X6/6處具有穩(wěn)壓電源）。

The drive controller controls the motor holding brake. As long as this
function is not available from the control manufacturer it is necessary to
use an external device. In this case, connect the external brake voltage
directly to the brake connections BR+ and BR- which are on the motor
and switch these using an external circuit.When using ADP motors the temperature sensor cable can
not be connected to X6. Instead a 750R resistor should be
connected between X6.1 and X6.2.
With ADP motors the temperature signal transmitted via the
motor cable is only used in the controller.
Note: If a motor holding brake is used, then it is necessary to
connect an external 24V three-phase voltage source.
The current consumption of the holding brake is listed in the project
planning manual of AC motors.
Note: The internal brake control switch can only supply 2A
maximum.
The AC motor holding brake is not a working brake. It wears down after
about 20,000 motor revolutions against the closed brake.
Note: To release a holding brake in an MHP AC servo motor, apply
the DC +24V +/- 10 % directly to the motor. The voltage to
release the brake must either applied to X6/3 (+24V) and X6/6
(0V) or directly to the motor. It must be ensured that the brake
will release even if longer motor power cables are used
(voltage drop with long motor power cables can be
compensated by increasing supply voltage (up to DC +26.5V)
and/or with a regulated voltage supply at X6/3 and X6/6).
XS1, shield attachment for motor cable
The entire motor cable shield is placed on shield bracket XS1 using the
supplied clips. The cable diameter is matched by selecting an appropriate
clip bracket on the mounting panel. The output direction of the cable can
be either vertical or horizontal and this can be selected and set by moving
the mounting panel as needed.t1: depends on parametrized function of the drives
t2: depends on the reaction time of the PLC
The following values are valid for a maximum additional capacitance of 10 mF
or 20 mF respectively!
t3: on-delay of K1 mains contactor in the unit (max. 3,6 ms *1)
t4: time to build up DC bus voltage (max. 4,1 s *1)
