Description Example
value Name Index
Sets the number of HTL pulses per re-
volution for safety pulse encoder 1. 2048 Pulses/revolu-
tion 92.10
Adjust the default value to meet the
safety pulse encoder in use. Make sure
that the value is according to the en-
coder nameplate.
Sets the maximum pulse frequency
range of encoder 1. Adjust the default
value to meet the motor and safety
pulse encoder in use. You can use this
formula to define the value:
r_max ·
ppr_enc + 10%, where
300 kHz Accepted pulse
freq of encoder
1 92.17
• r_max : the maximum motor speed
(rpm) used in the application (or
the motor nominal speed)
• ppr_enc : pulses/revolution of the
safety pulse encoder (parameter
92.10 ).
￭ Notes
ACS880-07/17/37 and ACS880-17LC/37LC drives with Q978:
In motor overtemperature situations, the FSO module also opens the
main contactor/circuit breaker.
ACS880-07/17/37 and ACS880-17LC/37LC drives with Q978
or +Q979: The FSO module is configured so that after the safety
function activation, the user must reset the FSO module manually
with the emergency stop reset button. The user must also reset the
FSO module with the emergency stop reset button after motor
overtemperature situations. The indication lamp on the reset button
is on. Do not change this setting.
Mechanical brake control
If you use a mechanical brake with the motor thermal protection
circuit, pay special attention to the control of the mechanical brake.
