1. Warning Function
Always check the control unit, motor, spindle and the condition of the cooling air prior to
use. This will help prevent system errors that will result in undesired operating conditions.
(1) The Warning LED [
20
] will flash.
(2) The Warning Code (listed in Table 2) will be displayed on the Digital Speed Indicator [11].
(3) A Warning Signal is output to the Warning Signal (PIN No. 20 : WARNING) of
Input/Output Connector A.
2. Detection of unsafe operating conditions
Always check the control unit, motor, spindle and the condition of the cooling air prior to
use. This will help prevent system errors that will result in undesired operating conditions.
When an Error Occurs the following events happen :
(1) Motor stops
(2) The Error LED [
19
] will flash.
(3) Error Code (listed in Table 3) will be displayed on the Digital Speed Indicator [
11
].
(4) An Error signal is output to the Error Signal (PIN No. 8 : ERR) of Input/Output Connector.

Safety Relay Signal
PIN No. 3-11, 4-12
• The Safety Relay will be ON or OFF depending on the state of the Emergency Stop Signal
PIN1-9.
• When there is continuity between PIN3 (SAFE-1A) and PIN11 (SAFE-1B) or between PIN4
(SAFE-2A) and PIN12 (SAFE-2B) the motor is off. If there is no continuity between these
pairs of pins then the system is operating normally.
• If the Emergency Stop Signal is OFF (Open) the Safety Relay will be OFF (Open) and the
motor power will be interrupted and the motor will stop.
• If the ‘a’ contacts of the Safety Relay are welded together by an over load or short circuit
the ‘b’ contacts’ separation are maintained with more than 0.5mm spacing by the relay’s
recoil mechanism.
• The voltage/current specifications of PIN3-11 & PIN4-12.
Applied Voltage (V max) 30VDC
Working Current (Ip) 2A
