Emergency Stop Gain Correction operates in the same manner as the previously described Acceleration/Deceleration
Polarity Gain Correction in section 7.4.2 with a separate set of gain correction parameters. The Emergency Stop gain
correction is active while the Emergency Stop contact (Terminals 8 & 12) is ON. When the Emergency Stop contact is
turned ON, the Control Output is increased by the Emergency Stop Correction. When the Diameter Measuring Func-
tion is enabled, the effective Emergency Stop Correction is proportional to the measured diameter vs. maximum diameter;
otherwise the full Emergency Stop Correction is applied. While the Emergency Stop Contact is active, the Proportional
Gain and Integral Time are set by Parameters No. 34 – 37.
Activating Conditions
• Emergency Stop Contact is ON (Terminals 8 and 12)
• Memory DIP Switch (MSW0-1, 2): Set to “EMS” (default value)
Related Parameters
• Memory DIP Switch MSW0-3: Diameter Measuring Function
Disabled: Full Emergency Stop Correction
Enabled: Emergency Stop Correction proportional to maximum diameter
• No. 34 Proportional Gain 2 ( + deviation )
• No. 35 Integral Time 2 ( + deviation )
• No. 36 Proportional Gain 2 ( - deviation )
• No. 37 Integral Time 2 ( - deviation )
• No. 38 Emergency Stop Correction
