9.2.2 Revolution Direction Specifications 
This section explains the direction of revolution for the Servomotor and the encoder respectively. 
 
(1) Servomotor 
The Servomotor rotates counterclockwise (forward revolution) when viewed from the load side after a 
command to increase a position command is input.

9.2.4  Holding Brake Specifications 
An optional holding brake is available for each motor.   Since this brake is used for holding, it cannot be 
used for braking except in an emergency.    Turn brake excitation on and off using the holding brake timing 
signal output. 
When the signal is used, forcibly set the command to 0 min
−1 in the Servo Amplifier while the brake is 
released. 
To externally control the holding brake, a response time as in Table 9-20 is required.    When...
