Word Description
FOC49 Proportional Gain for Pressure Control [30]
FOC50 Integral Gain for Pressure Control [27] or [28]
FOC51 Derivative Gain for Pressure Control [26] or [21]
FOC52 Proportional Gain for Velocity Control [28]

Profile Pressure Alarm Setpoint
Word Description
FOC57 Profile High Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when executing the
First Clamp Open Profile. The module sets alarm status bit SYS06-B09 when clamp pressure equals or exceeds this entry during
the First Clamp Open Profile. A zero entry inhibits SYS06-B09.
FOC58 - 64 Open
