2) The proportion of timer points to counter points can be
changed using a system register 5.
3) Precision of calender timer:
At 0
C/32 F, less than 139 second error per month.
At 25
C/77 F, less than 72 seconds error per month.
At 55
C/131 F, less than 169 seconds error per month.
This accuracy is considered to be the worst fluctuation
coefficient value based on fluctuations in the normal voltage of
5V and the battery backup voltage of 3V. Also, F157 and F158
(time/date addition and subtraction instructions) cannot be
used.
4) Although it has adequate tolerance noise, it is recommendable
to make the user program to execute retransmission (in order
to improve reliability of the communication when a
communication error occurs due to excessive noises or when
a receiver equipment cannot receive data temporarily.) The
driver IC for the RS232C is in full conformance with
EIA/TIA−232E and CCITT V.28 standards.
5) The combinations 1 phase × 2 channels and 2 phases × 1
channel are also possible for the high−speed counter.
6) The internal relay, data register, and timer/counter hold areas
of the T32CT control unit (10 k step type) can be changed by
the system registers. The number of points in the table is the
value when the system registers are initial values.
7) The max. counting speed (10kHz) is the counting speed with a
rated input voltage of 24V DC and an ambient temperature of
25°C. The counting speed (frequency) will decrease depending
on the voltage and temperature.
8) If both reset inputs X0 and X1 are reset, X2 will be the reset
input of X1. In the same way, for X3 and X4, X5 acts as the
reset input of X4.
9) With a CPU of Ver. 1.2 or a subsequent version, the frequency
will be 0.15Hz to 1kHz.
10) The maximum is 9.5kHz when the positioning control
instruction (F168) is executed.
11) Precautions when using the battery backup function
Secondary (chargeable) battery is used as backup battery in
the FP0 T32C control unit. The battery is not charged before
the unit is shipped, so please make sure that the built−in
backup battery have been charged before using the unit.
12) The program, system registers and the hold type areas
(internal relay, data register and counter) are backed up by
the built in EEPROM.
