7. TROUBLESHOOTING
No. Name
Encoder diagnosis error
7B
(safety observation function)
Functional safety unit
7C communication diagnosis error
(safety observation function)
7D Safety observation error
Note 1. The following shows stop methods. For other stop methods, refer to section 4.5.2 (3) (a).
DB: Stops with dynamic brake. (Coasts for the servo amplifier without dynamic brake.)
SD: Forced stop deceleration
STO/DB: Dynamic brake stop with STO function
SS1/SD: Forced stop deceleration with SS1 function
SS1/EDB: Electronic dynamic brake stop (available with specified servo motors)
Refer to the following table for the specified servo motors. The stop method for other than the specified servo
motors is SS1/DB.
Series
HG-KR
HG-MR
HG-SR
2. This is applicable when [Pr. PA04] is set to the initial value. The stop system of SD can be changed to DB using [Pr. PA04].
[Pr. PA04] is a parameter for servo amplifiers.
3. Reset this while all the safety observation functions are stopped.
4. The SSM function will be disabled and each output device will turn off.
(2) Warnings
No. Name
95 STO warning
E6 Servo forced stop warning
Note 1. The following shows stop methods.
STO/DB: Dynamic brake stop operating the STO function
SS1/SD: Forced stop deceleration operating the SS1 function
2. This is applicable when [Pr. PA04] is set to the initial value. The stop method of SS1/SD can be changed to SS1/DB with [Pr.
PA04]. [Pr. PA04] is a parameter for servo amplifiers.
3. The SSM function will be disabled and each output device will turn off.
