(factory setting)
Write Description [Setting range]
57 2057 MEAS_PRESS_
SUPPLY
0kPa — Air supply pressure (%); a parameter set by auto
tuning (Valid when an optional pressure sensor is
specified.)
58 2058 MEAS_SPRING_
RANGE
0kPa — Spring range of valve; a parameter set by auto
tuning (Valid when an optional pressure sensor is
specified.)
59 2059 CONTROL_DIR 2 — Defines the acting direction of the feedback loop:
1 = direct
2 = reverse
60 2060 THETA_HI (*1)(*2) + 0.2 rad. — Upper angle signal limit of position sensor (in
radians)
61 2061 THETA_LO (*1)(*2) -0.2 rad. — Upper angle signal limit of position sensor (in
radians)
62 2062 THETA_P (*1)(*2) 0 rad. — Angle signal equal to 50 % from position sensor
(in radians)
63 2063 TRAVEL_CALIB_
EXEC
1 O/S Switch for starting a travel calibration.
64 2064 TRAVEL_CALIB_
RESULT
1 — Indicates the result of a travel calibration.
65 2065 OPEN_STOP_ADJ — — Not used for YVP110.
66 2066 AUTO_TUNE_EXEC 1 O/S Switch for starting auto tuning.
67 2067 AUTO_TUNE_
RESULT
1 — Indicates the result of auto tuning.
68 2068 AUTO_TUNE_STATE 0 — Indicates auto tuning sequence number.
69 2069 SERVO_RET_TO_
DFLT
1 O/S Writing 2 to this parameter resets all control
parameters to the defaults:
1 = off
2 = set (to the defaults)
70 2070 ADVAL_FW — — Digital value of valve control signal, setpoint
equivalent to A/D value of valve position signal.
71 2071 ADVAL_BW — — A/D value of valve position signal
72 2072 ADVAL_PRESS — — A/D value of pressure from sensor
73 2073 ADVAL_T — — A/D value of temperature from sensor
74 2074 TOTAL_CYCLE_
COUNT
0 O/S Total number of cycles. To reset the count, write 0.
75 2075 CYCLE_DEADBAND 0.25% — Dead band of cycle counting
76 2076 CYCLE_COUNT_LIM 2^32-1 High-limit alarm setting for TOTAL_CYCLE_
COUNT. When TOTAL_CYCLE_COUNT has
reached this setting, a block alarm is generated.
77 2077 TOTAL_TRAVEL 0 O/S Total amount of travel. To reset the count, write 0.
78 2078 TRAVEL_
DEADBAND
0.25% Dead band of travel integration
79 2079 TRAVEL_LIM 2^32-1 High-limit alarm setting for TOTAL_TRAVEL.
When TOTAL_TRAVEL has reached this setting,
a block alarm is generated.
80 2080 TOTAL_OPEN_TIME 0 hour Total time other than counted for TOTAL_CLOSE_
TIME. To reset the count, write 0.
81 2081 TOTAL_CLOSE_
TIME
0 hour Total time where valve position is equal to or less
than OPEN_CLOSE_THRESHOLD. To reset the
count, write 0.
82 2082 OPEN_CLOSE_
THRESHOLD
0.25% — Threshold value for TOTAL_OPEN_TIME and
TOTAL_CLOSE_TIME.
83 2083 OPEN_TIME_LIM 2^32-1 hours High-limit alarm setting for TOTAL_OPEN_TIME.
When TOTAL_OPEN_TIME has reached this
setting, a block alarm is generated.
84 2084 CLOSE_TIME_LIM 2^32-1 hours High-limit alarm setting for TOTAL_CLOSE_TIME.
When TOTAL_CLOSE_TIME has reached this
setting, a block alarm is generated.
