During a direction change, the brake is kept open all the time. D2L decelerates the motor to a stop according
to the set deceleration time when the run command is switched off, so the brake is used only as a holding
brake. This way brake wear is minimized. Only if a failure occurs or the emergency stop button is pushed, the
brake closes immediately stopping the motor and the load.
Models 002F-011F have a built-in REC12 brake control unit, which is a line voltage half-wave rectifier. The
half-wave type rectifier reduces losses and is enough to open the brake. There is a contactor to switch the line
voltage on and off.
Models 015F-055F have a built-in ESD141 brake control unit, which is a line voltage full/half-wave rectifier.
Full-wave rectification is used to open the brake quickly. Then, the rectifier changes to a half-wave type, which
reduces losses, but is enough to keep the brake open. There is a contactor to switch the line voltage on and
off. The same contactor also disconnects the DC-voltage directly from the brake coil, which guarantees that
the brake closes fast.
Model 055F includes a 3-phase AC-supply for the brake control. D2L controls this line and it is protected by an
adjustable circuit breaker (max. 4.0A). When a shoe brake is used, brake closing is speeded up by capacitors.
They are connected in parallel with the brake via the brake contactor NC-contacts. The connection is partially
ready in D2L. Only the capacitors must be added outside D2L. This connection can also be used to control 2-
phase disk brakes or a separate KA372B brake control unit.
1.8 EMC
The shortening "EMC" stands for the Electro Magnetic Compatibility. According to the EMC directive "the
apparatus shall be so constructed that:
•
The electromagnetic disturbance it generates does not exceed a level allowing other apparatus to
operate as intended
•
The apparatus has an adequate level of intrinsic immunity of electromagnetic disturbance to enable it
to operate as intended."
Declaration of conformity
With the declaration of conformity the manufacturer informs that device is manufactured to fulfill
required EMC standards.
CE-mark
The CE marking is a declaration by a manufacturer or importer located in the European Economic
Area that a product complies with the safety and health requirements of the directive in question. The
manufacturer demonstrates for the authorities that the product complies with the safety requirements
within the EU.
Environments
Immunity and emission requirements are divided
in two levels in the product standard according to
the environments.
First environment means environment that
includes domestic premises and also
establishments directly connected to a low-
voltage power supply network.
PDS
Second environment means environment that
includes all establishments other than those
directly connected a low-voltage power supply
network
PDS

61800-3 Amendment 11 (2000) for the second environment.
•
