SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
SI P2: Brake control defective
OFF2
IMMEDIATELY (POWER ON)
The "Safety Integrated" function integrated in the drive on the Motor
Module (MM) has detected a brake control fault and initiated a STOP
A.
-- The motor cable shield is not correctly connected.
-- Defect in the brake control circuit of the Motor Module.
Fault value (r0949, interpret decimal):
10:
Fault for "Open brake"
-- Parameter p1278 incorrectly set
-- Brake not connected or interrupted cable (check whether for p1278
= 1 and p9602/p9802 = 0 (SBC switched--out) the brake opens).
-- Ground fault, brake cable
30:
Fault for "Close brake"
-- Brake not connected or interrupted cable (check whether for p1278
= 1 and p9602/p9802 = 0 (SBC switched--out) the brake opens).
-- Short--circuit in the brake winding
40:
Fault in the "Brake closed" state
60, 70:
Fault in the brake control of the Control Unit or communication error
between the Control Unit and Motor Module (brake control).
81:
Safe Brake Adapter: Fault for "Brake closed" operation
82:
Safe Brake Adapter: Fault for "Open brake".
83:
Safe Brake Adapter: Fault for "Close brake".
84,85:
Safe Brake Adapter:
Fault in the brake control of the Control Unit or communication error
between the Control Unit and Motor Module (brake control).
90:
Brake released for service purposes (X4).
91:
Fault for "Open brake".
-- Brake not connected or interrupted cable (check whether for p1278
= 1 and p9602/p9802 = 0 (SBC switched--out) the brake opens).
Check parameter p1278 (with SBC, only p1278 = 0 is permissible)
-- Select Safe Torque Off and then deselect again.
-- Check the motor holding brake connection.
-- Check the function of the motor holding brake.
-- Check whether there is a DRIVE--CLiQ communications error
between the Control Unit and the Motor Module involved and if
required, carry out a diagnostics routine for the faults identified.
