Parameter No.
E20, E21, E27
Maintenance timer counted up (E20, E21, E27 = 84: MNT)
To output this signal, allocate "84: MNT (Maintenance timer counted up)" to Output Terminal [DO1]
Function Selection (E20), Output Terminal [DO2] Function Selection (E21) and Output Terminal [ROA,
ROB] Function Selection (E27).
The signal is output when 1st Startup Count for Motor (H44) reaches the value set at 1st Preset Start-
up Count for Motor Maintenance (H79), or 1st Cumulative Motor Run Time (H94) reaches the value
set at 1st Motor Maintenance Interval (H78).
This function is exclusively for the 1st control. The maintenance timer signal is not output even if 2nd
Cumulative Motor Run Time (A51)/2nd Startup Counter for Motor (A52) exceeds the set time period or
set number of times.
<For half-yearly maintenance>
1st Cumulative Motor Run Time (H94)
H78 = 876
(8760 hours = 1 year)
H78 = 438
(4380 hours = 6 months)
Maintenance timer
"MNT"
When the maintenance time is reached, or when the set number of startups for maintenance is
reached, again set a numeric value at 1st Motor Maintenance Interval (H78) or 1st Preset Startup
Count for Motor Maintenance (H79), and press the
measurement of the time period or the number of startups.

Logic Operation Output Signal (LOG1 to LOG3)
Logical operations (AND, OR, XOR) are performed on signals that can be allocated to output terminals
[DO1], [DO2] and [ROA, ROB], and the result can be output from output terminals. Set "206: LOG1
(Logic operation output 1)," "207: LOG2 (Logic operation output 2)," or "208: LOG3 (Logic operation
output 3)" at Output Terminal [DO1] Function Selection (E20), Output Terminal [DO2] Function Selec-
tion (E21) and Output Terminal [ROA, ROB] Function Selection (E27). However, "206: LOG1 (Logic
operation output 1)" to "208: LOG3 (Logic operation output 3)" cannot be selected for the operation
target data.
