3.2 J1 - Terminal Block

The J1 terminal block consists of 4 terminals at the base of the E94ZAHBK2 Motor Brake Module. The two left

terminals are for the external 24 VDC power supply that will energize the brake coil. The two terminals on the

right are to be wired to the brake coil. Table 2 lists the Terminal pins from right to left looking at the module,

numbered 1 to 4

4 Operation

There are two methods of utilizing this module. The ﬁrst is by assigning Ouput 2 to the special purpose function

“Brake”, see section 5.2.2 of the PositionServo Users Manual. This will automatically turn the output on when

the drive is enabled and turn the output off when the output is disabled. The typical time sequence is shown

in Figure 3

The second method is to use the indexer program to toggle OUT2. The delay times for releasing and engaging

the holding brake can be controlled with some ﬂexibility.

The Motor Brake Module is optically isolated from the PositionServo drive. When the output is on, the brake will

be released and the green LED on the module will be illuminated.
