Bfm #37 (Ch1) And Bfm #56 (Ch2): Output Limiter Upper Limit Bfm #38 (Ch1) And Bfm #57 (Ch2): Output Limiter Lower Limit - Mitsubishi Electric MELSEC FX2N-2LC User Manual

FX2N-2LC Temperature Control Block
7.2.21 BFM #37 (CH1) and BFM #56 (CH2): Output limiter upper limit
BFM #38 (CH1) and BFM #57 (CH2): Output limiter lower limit
In BFM #37 and BFM #56, set the output limiter upper limit of CH1 and CH2 respectively. In
BFM #38 and BFM #57, set the output limiter lower limit of CH1 and CH2 respectively.
Use these BFMs when setting the upper limit and the lower limit for the setting of the control
output value (MV) (BFM #5, BFM #6).
The allowable set range of the upper limit is from the output limiter lower limit to +105%. The
allowable set range of the lower limit is from -5.0% to the output limiter upper limit.
