How to configure SSM
Example: The figure below shows an example of an SSM1 set-up. Only the positive
SSM1 limit is configured.
• SSM1 function activated
(SSMx.01 SSM1 activity and version = Version 1)
• redundant SSM activation button connected to input
(SSMx.11 SSM1 input = DI X113:2 & X114:2)
• single output connected (SSMx.14 SSM1 output = DO X114:7)
• SSM1 positive limit 1800.0 rpm (SSMx.13 SSM1 limit positive = 1800 rpm)
• SSM1 negative limit 0 rpm (SSMx.12 SSM1 limit negative = 0 rpm).
• When an encoder is not used: Time to zero speed: 1500 ms. This is the
estimated time in which the motor coasts to a stop from the maximum speed
(STO.14 Time to zero speed with STO and modoff = 1500 ms, not shown in the
figure).
SSMx.11
= DI X113:2 &
X114:2
SSMx.14
= DO X114:7
SSMx.13 = 1800 rpm
