6F2T0207 (0.01)GRE200 (5,6)- 319 -2.28.2 Motor statusGenerally, large motor current enters when the motor is started. After that, the motor current(less than the motor rated current) enters in the situation that the motor is running normally.MOT function judges whether the motor status is “Stop”, “Start-up”, or “Running” using themotor current value and the motor start-up time.(i) Judgement of motor statusUsual motor status transitions mode-1 and mode-2 are shown in Figure 2.28-1 and Figure2.28-2. In addition, the condition for motor status judgement is shown in Table 2.28-5. Mainly,one type of motor current values† is used to judge the motor status.†One is whether the motor current value is falling below 5% of motor rated current (5%of [Mot-Ir]) or exceeding. The other is whether the motor current value is falling below150% of motor rated current (150% of [Mot-Ir]) or exceeding.Table 2.28-3 Condition for motor status judgmentMotor statuses Condition for motor status judgmentStop When the motor current value is falling below 5% of [Mot-Ir]‡, it isjudged motor status as "Stop"Start-upFrom the time when the motor current value exceeds 5% of [Mot-Ir]until the conditions of following [Mode-1] or [Mode-2], it is judgedmotor status as "Start-up".[Mode-1] In the mode in which the motor current value falls below150% of [Mot-Ir] before the motor start-up time elapses, it isuntil the motor start-up time§ elapses.[Mode-2] In the mode in which the motor current value does not fallbelow 150% of [Mot-Ir] even after the motor start-up time§elapses, it is until the motor current value falls below 150%of [Mot-Ir].Running From the end of “start-up” until the motor current falls below 5% of[Mot-Ir], it is judged motor status as "Running".Overload When the motor current exceeds the operating value of thermaloverload relay, it is judged motor status as "Overload".‡Note:If 5% of [Mot-Ir] is less than 0.1A, the threshold value may as well be 0.1A.§Note:The length of motor start-up time can be set with setting [T-Mot-Start].Table 2.28-4 Time settingSetting items Range Unit Contents DefaultT-Mot-Start 0.10 - 300.00 s Motor start-up time 60.0
